Controlling Pt Crystal Defects on the Surface of Ni–Pt Core–Shell Nanoparticles for Active and Stable Electrocatalysts for Oxygen Reduction

A strategy of direct growth of Pt on Ni was used to create and control Pt crystal defects on the surface of Ni–Pt core–shell nanoparticles. The control over the types of defects was easily achieved by changing the surfactant system. In this work, two types of crystal defects have been introduced into Ni–Pt core–shell nanoparticles: polycrystalline shells with multiple grain boundaries and step-edge shells with undercoordinated atoms at corners and steps. We show that the step-edge shell has a higher specific activity for the oxygen reduction reaction (ORR), while the thinner polycrystalline shell results in a higher activity per mass and stability. Our results suggest that Ni–Pt core–shell nanoparticles with a thin Pt shell that have high density of crystal defect should be targeted for high performance ORR catalysts.

Atomically Dispersed Fe on Nanosheet-linked, Defect-rich, Highly N-Doped 3D Porous Carbon for Efficient Oxygen Reduction

Exploring cost-effective and high-performance oxygen reduction reaction(ORR) electrocatalysts to replace precious platinum-based materials is crucial for developing electrochemical energy conversion devices but remains a great challenge. Herein, Fe single atoms anchored on nanosheet-linked, defect-rich, highly N-doped 3D porous carbon(Fe-SAs/NLPC) electrocatalysts were obtained by pyrolyzing salt-sealed Fe-doped zeolitic imidazolate frameworks(ZIFs). NaCl functions both as pore-forming agent and closed nanoreactor, which can not only lead to the formation of defects-rich three-dimensional interconnected structures with high N-doping content to expose abundant active sites, promote mass transfer and electron transfer, but also facilitate the effective incorporation of Fe to form Fe-Nx active sites without aggregation. These unique characteristics render Fe-SAs/NLPC outstanding electrocatalytic activity for ORR, with one-set potential of 0.96 V and high kinetic current density(jK) of 33.32 mA/cm2 in alkaline medium, which surpass the values of most nonprecious-metal catalysts and even commercial Pt/C.

Study on the Effect of Surface Area on the Oxygen Reduction Reaction Performance of Perovskite Catalyst for Lithium-Oxygen Batteries

Lithium oxygen batteries have been recognized as one of the next-generation power sources, capable of supplying power for a long time even in an independent extreme environment. In spite of the theoretical advantage, Li-O2 batteries face technical and economic challenges that must be addressed to promote them as commercially variable technologies for future energy system. Above all, battery performance largely depends on the activities of the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) of the cathode during discharge and charge, respectively. The undesirable overpotential caused by sluggish reaction kinetics associated with the ORR and OER greatly limit the current performance of Li-O2 batteries, which must be improved by efficient catalyzing the reactions. Among the numerous catalysts, perovskite oxides have attention for candidate electro catalyst for Li-O2 batteries due to their high electronic/ionic conductivity, high electrochemical stability, and catalytic activity. Especially, La0.6Sr0.4Co0.2Fe0.8O3(LSCF) is considered as a typical catalyst for Li-O2 batteries, which can provide high oxygen surface exchange coefficient for fast kinetics at the gas/electrode interface. The surface area is significantly related on the ORR and OER performance, which influences on the active area for reactions. In this study, we have tried to utilize a simple high energy ball milling process to investigate the electrochemical properties of LSCF catalyst. Through the BET analysis, it was confirmed that the specific area significantly was increased after ball milling due to the reduced particle size, obtaining the optimized milling time with the higher ORR performance. The electrochemical activities have been measured with rotating disk electrode (RRDE) method. Well-ball milled LSCF catalyst has resulted in the enlargement of specific surface area and increased defective sites, which improve the catalytic activity.To investigate the influence of LSCF oxides on the ORR process, the performance of composite electrode with LSCF catalyst in LITFSI in ether solvents has been compared with a carbon based cathode (carbon nano tube(CM130)). From the discharge results, the composite electrode showed the superior performance as well as higher specific capacitance (more than 1.6 times) than carbon based electrode dye to the altered transport and reaction kinetics due to LSCF. In this study, we have proposed the processes of obtaining a catalyst with optimal electrochemical properties through a relatively simple process and applied it to electrode for lithium oxygen batteries.

Accessing Catalytically Active Ordered Intermetallics Compounds Via Electrochemically Driven Phase Transformations

The conversion of O2 to H2O is an important fuel cell reaction for the recovery of renewable electricity from chemical fuels. Alloys of Pt-group metals (PGMs) with transition metals have emerged as catalysts with enhanced activity and durability for the oxygen reduction reaction (ORR). To date, most studies focus exclusively on alloys that adopt a Face-centered cubic (FCC) or Face-centered tetragonal (FCT) crystal lattice. Under ORR operating conditions, these materials evolve from alloys to Pt core-alloy shell materials, in this case both the alloy core and Pt shell retains the CCP type crystal structure; indicating that materials can dynamically change during catalysis.Here we present the synthesis of Pd-Bi based ordered intermetallics by partial dealloying of a Bi rich alloy. We found that under ORR operation conditions, ß-PdBi2 which adopts a tetragonal lattice, transforms to Pd3B orthorhombic crystal structure; this transformation is mediated by oxidative Bi corrosion under potential cycling, and reconstruction of the atoms in the bulk. To the best of our knowledge, this is the first report of a material that exhibits an electrochemically driven, non-congruent phase transition among materials with different crystal structures. The resulting phase-converted Pd3Bi is stable and exhibits high performance for ORR. Phase-converted Pd3Bi outperform Pt and Pd metal, reaching mass activities of 2.6 A/mgPd, which is nearly 10X higher than Pt/C (~0.3 A/mgPt) and Pd/C (~0.2 A/mg) at 0.9 V vs the Real Hydrogen Electrode (RHE). The mass activity of Pd3Bi decreases by ~38% after 10,000 cycles, indicating that it is stable. Activation energy (Ea) determined by temperature dependent electro-kinetic measurements indicates that the activity enhancement on phase-converted Pd3Bi originates from anion-poisoning resistant behavior. These results establish that PGMs-based ordered intermetallics with low-symmetry crystal structures can be highly active and durable electrocatalysts.

Uniformly dispersed Fe3C (~5 nm) in Fe-N-doped carbon nanosheets derived from coal tar pitch as efficient electrocatalysts for oxygen reduction reaction

It is of great significance to rationally design and synthesis low-cost catalysts for oxygen reduction reaction (ORR) with excellent catalytic activity for the application of fuel cell devices. Herein, a facile and cost-effective strategy is developed to prepare iron-nitrogen-doped carbon nanosheets with uniformly dispersed Fe3C nanocrystals (~5nm) encapsulated in graphitic layers (Fe3C@Fe-N-CNSs) by pyrolyzing a mixture of ferrocene-containing coal tar pitch and melamine. The optimized Fe3C@Fe-N-CNSs catalyst shows significantly improved ORR catalytic activity (onset potential 1.04 V) and a much better methanol tolerance than that of commercial Pt/C (onset potential 1.02 V) in an alkaline medium. This work paves a path for the preparation of low-cost and high-performance ORR electrocatalysts for fuel cells.

B, N-doped ultrathin carbon nanosheet superstructure for high-performance oxygen reduction reaction in rechargeable zinc-air battery

Rational structure design, composition control and heteroatom doping are efficient strategies to achieve excellent electrocatalysts for the oxygen reduction reaction (ORR) in fuel cells or metal-air batteries. Herein, a facile and efficient approach to prepare ultrathin carbon nanosheet superstructure (BN/C) with high B, N-doping level by using sodium chloride (NaCl)-assisted pyrolysis method is proposed. The developed BN/C catalyst exhibits good catalytic activity for ORR in alkaline medium with a half-wave potential (E1/2) of 0.8 V, which is comparable to that of commercial Pt/C. The BN/C catalyst also shows much better long-term stability and satisfactory tolerance for the methanol crossover effect. This excellent performance is attributed to the structure and composition characteristics of BN/C, including the large surface area (1085 m2 g−1), hierarchically porous structure, the synergistic effect of the B, N co-doping and high content of ORR active species. Significantly, the B element with electron-deficient property in BN/C can create more charged sites favorite for O2 adsorption and thus accelerate reaction kinetics in ORR. Furthermore, a rechargeable Zn-air battery device comprising BN/C catalyst and RuO2 with a liquid electrolyte shows superior performance with an open-circuit potential of ∼1.36 V, a peak power density of ∼115 mW cm−2, as well as excellent durability (1000 cycles for 14 days of operation). Moreover, a flexible solid-state Zn-air battery containing BN/C catalyst and RuO2 shows good cycling durability under different bending states, indicating the excellent practicability in wearable devices.

Pt/CoFe2O4-C hollow ball as efficient bifunctional electrocatalyst for Zn-air batteries

Development of efficient electrocatalysts for Zn-air batteries is vital for energy storage and conversion. The activities of oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are essential for the Zn-air battery (ZAB) application. Here, we synthesized the hollow ball spinel structural of Pt/CoFe2O4-C, which exhibited high ORR performance, close to commercial Pt/C. Simultaneously, the OER performance of Pt/CoFe2O4-C was slight better than that of the commercial IrO2. Thus, the prepared (wt:0.1) Pt/CoFe2O4-C was applied in the homemade ZABs, whose open circuit voltage was as1.483 V, approaching the performance of the mixture of the commercial Pt/C and IrO2 (1.508 V). Moreover, the discharge/charge voltage gap for the sample was as low as 1.288 V at 50 mA cm−2, outperforming the mixture of Pt/C and IrO2 (1.51 V). Remarkably, the small voltage difference of Pt/CoFe2O4-C was shown as 0.401 V after 12 h Zn-air battery charge/discharge testing under 30 mA cm−2.

Cobalt and nitrogen doped porous carbon nanofibers as an efficient electrocatalyst for high performance oxygen reduction reaction

Efficient oxygen reduction reaction (ORR) electrocatalysts are critical for fuel cells. Herein, we report a facile synthetic method to prepare Co–N–C porous nanofibers (Co–N-CNFs) for high performance ORR electrocatalyst. Specifically, Polyacrylonitrile/Bimetallic (Cobalt and Zinc) ZIFs (PAN@BZIFs) hybrid is obtained by electrospinning and finally resulting in Co, N doped carbon nanofibers after pyrolysis. Electrochemical measurements demonstrate that it possesses remarkable ORR performance, superior stability and methanol tolerance under alkaline condition compared to commercial Pt/C catalyst. In this Co–N–C system, the ratio of Co/Zn in BZIFs and temperature of pyrolysis are confirmed as the important factors of specific surface area, graphitization and even ORR property. Thereby, through changing them, the best electrocatalytic activity was acquired with the ratio equals to 0.2 and pyrolyzing at 800 ℃. In addition, the excellent catalytic property can be attributed to the synergic coupling pores and hierarchical pore structure.

Pt nanowire/Ti3C2Tx-CNT hybrids catalysts for the high performance oxygen reduction reaction for high temperature PEMFC

The activity of catalyst could be enhanced by the temperature rising, so it is a suitable way to reduce the noble metal loading for the catalyst. However, the corrosion of carbon supports will be remarkable in the high temperature proton exchange membrane fuel cells (HT-PEMFC, >100 °C). This report demonstrated a novel Ti3C2Tx and CNT hybrid material as the catalytic support, and Pt nanowires (Pt NWs) is loaded on the hybrid support to construct the catalyst for HT-PEMFC. The Pt NWs/Ti3C2Tx-CNT performs higher electrochemical activity, better stability than that of commercial Pt/C. The mass activity and specific activity of Pt NWs/Ti3C2Tx-CNT catalysts are 3.89 and 3.02 times as that of Pt/C, respectively. The power densities of HT-PEMFC showed 155.4 mW cm−2 and 182 mW cm−2 at 150 and 180 °C, respectively.

Design and synthesis of carbon nanofibers decorated by dual-phase TinO2n-1 nanoparticles with synergistic catalytic effect as high performance oxygen reduction reaction catalysts

As a green pollution-free reaction, oxygen reduction reaction (ORR) plays a significant role in many energy storage and conversion devices. Although commercial Pt/C possesses the highest ORR activity (especially in acidic medium), the high cost, low stability and poor methanol tolerance making the development of non-platinum electrocatalysts with high performance especially important. Herein, we design and synthesize a carbon nanofiber decorated by Ti4O7/Ti3O5 dual-phase nanoparticles (CNF/T4/T3) as ORR catalysts with excellent activity. With the employment of electrospinning followed by precisely controlled calcination process, the composite catalysts with uniform fibrous morphology can be obtained. Such CNF/T4/T3 composite catalysts exhibited an improved electrochemical performance with onset and half-wave potential of 0.91 V and 0.78 V respectively in alkaline solution. By comparing the catalytic performance with the pure T4 or T3 phase decorated on the same carbon nanofiber, it is found that the mixture of the two titanium sub-oxide phases can optimize the onset potential and limited current density at the same time. Density functional theory calculations suggest that different steps of ORR take place on T3 and T4 successively, which is the main reason of the excellent ORR performance for the dual-phase structure. This work provided a novel designing concept for the functional electrocatalysts using electrospinning technique for the application of energy storage and conversion.

Atomic Dispersion and Surface Enrichment of Palladium in Nitrogen-Doped Porous Carbon Cages Lead to High-Performance Electrocatalytic Reduction of Oxygen.

Metal-nitrogen-carbon (MNC) nanocomposites have been hailed as promising and efficient electrocatalysts toward oxygen reduction reaction (ORR), due to the formation of MNx coordination moieties. However, MNC hybrids are mostly prepared by pyrolysis of organic precursors along with select metal salts, where part of the MNx sites are inevitably buried in the carbon matrix. This limited accessibility compromises the electrocatalytic performance. Herein, we describe a wet-impregnation procedure by facile thermal refluxing, whereby palladium is atomically dispersed and enriched onto the surface of hollow, nitrogen-doped carbon cages (HNC) forming Pd-N coordination bonds. The obtained Pd-HNC nanocomposites exhibit an ORR activity in alkaline media markedly higher than that of metallic Pd nanoparticles, and the best sample even outperforms commercial Pt/C and relevant Pd-based catalysts reported in the literature. The results suggest that atomic dispersion and surface enrichment of palladium in a carbon matrix may serve as an effective strategy in the fabrication of high-performance ORR electrocatalysts.

Bionic Structural Design and Electrochemical Manufacture of WC/N-Doped Carbon Hybrids as Efficient ORR Catalyst

A biomass-derived WC/N-doped carbon nanocomposite (denoted as WC/CC) with unique bionic structures, as an efficient electrocatalyst toward oxygen reduction reaction (ORR), is simply prepared via an eco-friendly and scalable method in molten NaCl-KCl using bulk-WS2 as a precursor. Corn crumb (CC) from by-products of food industry provides a fibriform N-containing biochar backbone by in situ pyrolysis, while W from the in situ electroreduction of WS2 would infiltrate into the carbon matrix under the effect of an applied electric field, contributing to the crystallization of WC along the fibers so that gnarled root-like composites are fabricated. The electrocatalytic behavior of the prepared materials are investigated in detail, the optimized sample (WC/CC-1/2) exhibits a decent onset potential of 0.865 V vs RHE for ORR in 1 M KOH solution and a four-electron pathway is dominant. This work provides a simple and feasible strategy for synthesizing high-performance ORR catalysts using biochar templates.

ZIF-8/LiFePO4 derived Fe-N-P Co-doped carbon nanotube encapsulated Fe2P nanoparticles for efficient oxygen reduction and Zn-air batteries

Iron-based oxygen reduction reaction (ORR) catalysts have been the focus of research, and iron sources play an important role for the preparation of efficient ORR catalysts. Here, we successfully use LiFePO4 as ideal sources of Fe and P to construct the heteroatom doped Fe-based carbon materials. The obtained Fe-N-P co-doped coral-like carbon nanotube arrays encapsulated Fe2P catalyst (C-ZIF/LFP) shows very high half-wave potential of 0.88 V in alkaline electrolytes toward ORR, superior to Pt/C (0.85 V), and also presents a high half-wave potential of 0.74 V in acidic electrolytes, comparable to Pt/C (0.8 V). When further applied into a home-made Zn-air battery as cathode, a peak power density of 140 mW·cm2 is reached, exceeds commercial Pt/C (110 mW·cm2). Besides, it also presents exceptional durability and methanol resistance compared with Pt/C. Noticeably, the preparation method of such a high-performance catalyst is simple and easy to optimize, suitable for the large-scale production. What’s more, it opens up a more sustainable development scenario to reduce the hazardous wastes such as LiFePO4 by directly using them for preparing high-performance ORR catalysts.

1D bamboo-like N-doped carbon nanotubes with encapsulated iron-based nanoparticles as an advanced Zn-air battery cathode electrocatalyst

Developing low-cost nonprecious metal catalysts with excellent activity and high durability for oxygen reduction reaction (ORR) is greatly imperative but challenging. Here, a high-performance ORR catalyst is designed based on in-situ grown bamboo-like N-doped carbon nanotubes with encapsulated Fe-based nanoparticles (Fe@B-NCNTs). The architecture of the 1D hierarchical porous nanotubes, large surface area with abundant defects and active sites, and strong coupling interactions between the enclosed metal-cluster core and the N-doped graphitic carbon shell synergistically enhance the electrocatalytic activity. As a result, Fe@B-NCNTs exhibit a more positive half-wave potential (0.898 V vs. the reversible hydrogen electrode, RHE), higher electrochemical stability and more superior resistance to methanol crossover than those of Pt/C in an alkaline electrolyte. Interestingly, when acting as a cathode electrocatalyst for a primary Zn-air battery (ZAB), Fe@B-NCNTs display a peak power density of ∼147 mW cm−2 and a first-class specific energy density of ∼921 Wh kgZn−1 at a discharge current density of 20 mA cm−2. Moreover, a proof-of-concept solid-state ZAB with bendable ability demonstrates the application potential in portable and wearable electronic devices.

3D nitrogen-doped carbon supported non-precious metals electrocatalyst for oxygen reduction reaction

Sluggish oxygen reduction reaction (ORR) is a rate-limiting step in some electrochemical devices such as fuel cells. Thus, the synthesis and development of high performance, inexpensive and durable catalysts for ORR is a necessity. Metallic nanostructures decorated heteroatoms-doped carbons have been recognized as excellent catalysts in energy applications. However, nitrogen-doped partially oxidized three-dimensional carbonaceous supports were seldom studied for ORR. Herein, the synthesis of low Fe-Co bimetallic contents deposited on three-dimensional (3D) activated carbon (AC) is reported as an efficient and cost-effective catalyst for ORR in alkaline electrolyte. In the present work, AC was thermally treated by direct heat in air at 430 °C to enhance its electrochemical activity through increasing structure deficiency. AC and nitrogen doped AC (N-AC) were used to synthesize Fe-Co/AC and Fe-Co/N-AC. In both Fe-Co/AC and Fe-Co/N-AC, low amounts of non-precious Fe and Co nanoparticles were deposited on carbonaceous substrates. The air oxidation process, for partially oxidation of carbon structure and catalyst post treatment, was used for introducing defects to the catalyst structure. The performance of synthesized samples was evaluated by ORR process in alkaline medium.

Cobalt Nanoparticles on Plasma-Controlled Nitrogen-Doped Carbon as High-Performance ORR Electrocatalyst for Primary Zn-Air Battery.

Metal–air batteries and fuel cells have attracted much attention as powerful candidates for a renewable energy conversion system for the last few decades. However, the high cost and low durability of platinum-based catalysts used to enhance sluggish oxygen reduction reaction (ORR) at air electrodes prevents its wide application to industry. In this work, we applied a plasma process to synthesize cobalt nanoparticles catalysts on nitrogen-doped carbon support with controllable quaternary-N and amino-N structure. In the electrochemical test, the quaternary-N and amino-N-doped carbon (Q-A)/Co catalyst with dominant quaternary-N and amino-N showed the best onset potential (0.87 V vs. RHE) and highest limiting current density (−6.39 mA/cm2). Moreover, Q-A/Co was employed as the air catalyst of a primary zinc–air battery with comparable peak power density to a commercial 20 wt.% Pt/C catalyst with the same loading, as well as a stable galvanostatic discharge at −20 mA/cm2 for over 30,000 s. With this result, we proposed the synergetic effect of transitional metal nanoparticles with controllable nitrogen-bonding can improve the catalytic activity of the catalyst, which provides a new strategy to develop a Pt-free ORR electrocatalyst.

Iron nanoparticles implanted metal-organic-frameworks based Fe–N–C catalysts for high-performance oxygen reduction reaction

The Fe–N–C active site containing non-precious metal catalysts (NPMCs) as the substitute to platinum-based catalysts are highly desired for oxygen reduction reaction (ORR) but it's a huge challenge to achieve such a high-performance and long term stabile one. In this study, the iron nanoparticles-implanted polyaniline (FeNPs@PANI) metal–organic–frameworks (MOFs) on reduced graphene oxide (rGO) has been synthesized through metal-ligand strategy via a simple chemical process. Strong interaction has been observed between FeNPs and nitrogen in PANI suggesting abundant Fe–N–C active sites in the FeNPs@PANI/rGO catalyst. Owing to the Fe–N–C active sites with less amount of oxygenated carbon in the molecular scale and mesoporous channels with the synergy of PANI and graphene in microscale, the FeNPs@PANI/rGO catalyst exhibits excellent catalytic activity and stability than the benchmark Pt/C catalyst towards ORR in respect to the onset potential and half-wave potential. Very importantly, the Fe–N–C active sites in FeNPs@PANI are comparatively better active against SCN− and methanol poisoning than bare FeNPs/rGO during ORR.

Zinc-Mediated Template Synthesis of Fe-N-C Electrocatalysts with Densely Accessible Fe-Nx Active Sites for Efficient Oxygen Reduction.

Owing to their earth abundance, high atom utilization, and excellent activity, single iron atoms dispersed on nitrogen-doped carbons (Fe-N-C) have emerged as appealing alternatives to noble-metal platinum (Pt) for catalyzing the oxygen reduction reaction (ORR). However, the ORR activity of current Fe-N-C is seriously limited by the low density and inferior exposure of active Fe-Nx species. Here, a novel zinc-mediated template synthesis strategy is demonstrated for constructing densely exposed Fe-Nx moieties on hierarchically porous carbon (SA-Fe-NHPC). During the thermal treatment of 2,6-diaminopyridine/ZnFe/SiO2 complex, the zinc prevents the formation of iron carbide nanoparticles and the SiO2 template promotes the generation of hierarchically pores for substantially improving the accessibility of Fe-Nx moieties after subsequent leaching. As a result, the SA-Fe-NHPC electrocatalysts exhibit an unprecedentedly high ORR activity with a half-wave potential (E1/2 ) of 0.93 V in a 0.1 m KOH aqueous solution, which outperforms those for Pt/C catalyst and state-of-the-art noble metal-free electrocatalysts. As the air electrode in zinc-air batteries, the SA-Fe-NHPC demonstrates a large peak power density of 266.4 mW cm-2 and superior long-term stability. Therefore, the developed zinc-mediated template synthesis strategy for boosting the density and accessibility of Fe-Nx species paves a new avenue toward high-performance ORR electrocatalysts.

Hierarchical Porous Manganese- and Nitrogen-Codoped Carbon Nanosheets Derived from Surface Modified Biomass as Efficient Oxygen Reduction Catalysts for Al-Air Batteries

Oxygen reduction reaction (ORR) is essential for metal-air batteries and fuel cells, and it is urgent to develop non-precious metal catalysts with low cost and high performance for ORR. Here we propose a new general strategy for preparing hieratical porous manganese- and nitrogen-codoped carbon (Mn–N–C) derived from low cost biomass. This strategy demonstrates that pre-oxidation of the biomass with an optimized temperature plays an essential role in forming the unique structure of Mn–N–C due to the modification of surface functional groups on biomass. The resultant Mn–N–C displays superior ORR performance in both alkaline and neutral electrolytes, which is comparable or even higher than that of the commercial Pt/C catalyst. The superior electrocatalytic performance is ascribed to the intrinsically efficient Mn-Nx active sites and the high surface area together with the hieratical pores exposing more active sites, which is also confirmed by the density functional theory calculation. Furthermore, the Al-air battery based on the Mn–N–C cathode shows a high working voltage and maximum power density, demonstrating promising potential for practical application. This approach provides a new insight for low-cost and high performance electrocatalysts for metal-air batteries.

Atomic Platinum Anchored on Fe‐N‐C Material for High Performance Oxygen Reduction Reaction

Development of highly active and stable catalysts to reduce the amount of Pt or replace Pt with nonprecious transition metal in acid of oxygen reduction reaction (ORR) is still an enormous challenge. Herein, we report anchoring atomic Pt particles on Fe/N‐doped carbon material (Pt1.1FeNC) are, for the first time, synthesized by the photodeposition method. The obtained Pt1.1FeNC electrocatalyst exhibits superior electrocatalytic activity and good stability for four‐electron oxygen reduction reaction (ORR) in an acidic electrolyte. Pt1.1FeNC electrocatalyst shows a half‐wave potential of 0.85 V vs. reversible hydrogen electrode (RHE) in 0.1 m HClO4 (0.83 V of 20 wt.‐% commercial Pt/C). After 10,000 cycles after, the catalysis active only decreases 20 mV. These are mainly due to the synergistic effect between Pt and Fe.
