Active MoS2-based electrode for green ammonia synthesis

Nitrogen electro-reduction under mild conditions is one promising alternative approach of the energy-consuming Haber-Bosch process for the artificial ammonia synthesis. One critical aspect to unlocking this technology is to discover the catalysts with high selectivity and efficiency. In this work, the N2-to-NH3 conversion on the functional MoS2 is fully investigated by density functional theory calculations since the layered MoS2 provides the ideal platform for the elaborating copies of the nitrogenase found in nature, wherein the functionalization is achieved via basal-adsorption, basal-substitution or edge-substitution of transition metal elements. Our results reveal that the edge-functionalization is a feasible strategy for the activity promotion; however, the basal-adsorption and basal-substitution separately suffer from the electrochemical instability and the NRR inefficiency. Specifically, MoS2 functionalized via edge W-substitution exhibits an exceptional activity. The energetically favored reaction pathway is through the distal pathway and a limiting potential is less than 0.20 V. Overall, this work escalates the rational design of the high-effective catalysts for nitrogen fixation and provides the explanation why the predicated catalyst have a good performance, paving the guidance for the experiments.

Removal of humic acid by peroxymonosulfate active with MnOx from the backwashing sludge of a filter for manganese removal

Finding a low-cost and high effective catalyst is an important problem in advanced oxidation processes (AOPs) based on PMS for organic matter removal. In this study, manganese oxide (MnOx) was extracted from the backwashing sludge of a filter for manganese removal and used to activate peroxymonosulfate (PMS) to remove humic acid from water. It was found that thermal treatment had significant effects on the structure and catalytic activity of MnOx. When MnOx was treated at 500 °C, it showed excellent catalytic activity and the removal rate of HA was up to 81.0%. Characterization indicated that the MnOx was converted from buserite and birnessite to α-MnOx after treated at 500 °C, and the specific surface area and the percentage of Mn (III) and Olatt on the surface increased significantly. The repeated utilization experiments indicated that the extracted MnOx still had high activity after reusing for 5 cycles. Quenching experiments showed that 1O2 was the dominant reactive oxygen species to oxidize HA in water. Finally, combining the results of FTIR and XPS spectra of MnOx before and after the catalytic reaction, the reaction mechanism was proposed: PMS was activated to be 1O2 by Mn (III) and Olatt in MnOx with a valence transformation between Mn (II), Mn (III) and Mn (IV) and HA was mainly oxidized by the non-radical pathway through 1O2. The experiments will provide a new strategy for recycling MnOx from backwashing sludge of the filter for Mn2+ removal to remove natural organic matter from water.

Advances in Spin Catalysts for Oxygen Evolution and Reduction Reactions.

Searching for high effective catalysts has been an endless effort to improve the efficiency of green energy harvesting and degradation of pollutants. In the past decades, tremendous strategies are explored to achieve high effective catalysts, and various theoretical understandings are proposed for the improved activity. As the catalytic reaction occurs at the surface or edge, the unsaturated ions may lead to the fluctuation of spin. Meanwhile, transition metals in catalysts have diverse spin states and may yield the spin effects. Therefore, the role of spin or magnetic moment should be carefully examined. In this review, the recent development of spin catalysts is discussed to give an insightful view on the origins for the improved catalytic activity. First, a brief introduction on the applications and advances in spin-related catalytic phenomena, is given, and then the fundamental principles of spin catalysts and magnetic fields-radical reactions are introduced in the second part. The spin-related catalytic performance reported in oxygen evolution/reduction reaction (OER/ORR) is systematically discussed in the third part, and general rules are summarized accordingly. Finally, the challenges and perspectives are given. This review may provide an insightful understanding of the microscopic mechanisms of catalytic phenomena and guide the design of spin-related catalysts.

Insight into the selective oxidation mechanism of glycerol to 1,3‐dihydroxyacetoneoverAuCu–ZnOinterface

AbstractDirectional regulation of polyol oxidation selectivity by constructing active sites with specific structure is a critical yet challenging problem. Herein, the specific Au‐based catalyst with efficient Au–Cu–ZnO interfacial active sites was successfully designed to promote selective oxidation of glycerol to 1,3‐dihydroxyacetone under mild conditions. X‐ray absorption spectroscopy revealed that the increased electron transfer between Au and Cu increases the content of Au+, resulting in the higher catalytic activity (turnover frequency: 402.5 h−1). Meanwhile, small AuCu alloy nanoparticles (ca., 2.7 nm) could be inserted into the ZnO lattice with the formation of Au(Cu)–O–Zn linkages, resulting in the enrichment of interfacial oxygen vacancies. These interfacial oxygen vacancies induce the activation and adsorption of the secondary hydroxyl group of glycerol on the interfacial active sites, improving the selectivity of 1,3‐dihydroxyacetone (83.4%). Furthermore,in situFourier transform infrared, structure‐dependent kinetics and density functional theory calculation demonstrated that Au–Cu–ZnO interfacial active sites could enhance the participation of OH* and oxygen vacancies in activating the OH and CH bonds, respectively, promoting the improvement of the catalytic performance. The outcome of this work offers new insights for the rational design of high effective catalyst for the selective oxidation of polyol.

High effective catalyst based on Ni doped TiO2 coated natural cotton fibers for catalytic reduction of organic pollutants

ABSTRACT A new type of nickel doped titanium oxide (Ni-TiO2) coated natural cotton fibers (CF) and Ni-TiO2 wrapped sodium alginate (Alg) hydrogel was developed for the efficient reduction of different contaminants. Ni-TiO2 was prepared by low-temperature method and coated on CF using Alg as a binder and entrapped inside Alg hydrogel. Ni-TiO2 coated CF (Ni-TiO2/CF) and Ni-TiO2 wrapped Alg (Ni-TiO2/Alg) were utilized for catalytic elimination of wastewater pollutants. Ni-TiO2/CF and Ni-TiO2/Alg were initially tested as nanocatalysts for reduction of potassium ferricyanide, 4-nitrophenol, congo red, and methylene blue (MB), and exhibited superior catalytic performance toward MB reduction. Different parameters such as catalyst amount, MB concentration, reducing agent amount, and recyclability were optimized. Comparatively, Ni-TiO2/CF revealed the best catalytic performance for MB reduction having the highest reaction rate constant (2.1564 min−1). Ultimately, the catalyst preserved superior activity in recyclability evaluation, confirming that Ni-TiO2/CF is a good catalyst for the efficient removal of MB up to four cycles. Ni-TiO2/CF can more easily be recovered compared to Ni-TiO2/Alg by easily pulling out the fibers from reaction medium, which is the main advantage of Ni-TiO2/CF. Moreover, Ni-TiO2/CF and Ni-TiO2/Alg were examined in real samples, providing the effective reduction of MB. The developed nanocatalyst offers a cost- and time-effective material for environmental safety purpose.

Remarkable catalysis of spinel ferrite XFe2O4 (X = Ni, Co, Mn, Cu, Zn) nanoparticles on the dehydrogenation properties of LiAlH4: An experimental and theoretical study

Safe, compact, lightweight and cost-effective hydrogen storage is one of the main challenges that need to be addressed to effectively deploy the hydrogen economy. LiAlH4, as a solid-state hydrogen storage material, presents several advantages such as high hydrogen storage capacity, low price and abundant sources. Unfortunately, neither thermodynamic nor kinetic properties of dehydrogenation for LiAlH4 can fulfill the requirements of practical application. Thus, a series of spinel ferrite nanoparticles such as XFe2O4 (X = Ni, Co, Mn, Cu, Zn, Fe) were prepared by using the modified thermal decomposition method, and then doped into LiAlH4 by using ball milling. Our results show that LiAlH4 doped with 7 wt% NiFe2O4 starts to release hydrogen at 69.1 °C, and the total amount of hydrogen released is 7.29 wt% before 300 °C. The activation energies of the two-step hydrogen release reactions of LiAlH4 doped with 7 wt% NiFe2O4 are 42.32 kJ mol−1 and 71.42 kJ mol−1, which are 59.0% and 63.6% lower than those of as-received LiAlH4, respectively. Combining the density functional theory (DFT) calculations, we reveal that both the presence of NiFe2O4 and in-situ formed Al4Ni3 in ball-milling decrease the desorption energy barrier of Al-H bonding in LiAlH4 and accelerate the breakdown of Al-H bonding through the interfacial charge transfer and the dehybridization of the Al-H cluster. Thus, the experimental and theoretical results open a new avenue toward designing high effective catalysts applied to LiAlH4 as a candidate for hydrogen storage.

Pt-based intermetallic compounds with tunable activity and selectivity toward hydrogen production from formic acid

Using first-principles methods, we studied formic acid dehydrogenation on the L11-type ordered Pt-based intermetallic compounds (i.e., X-Pt, X = Ag, Cu, Au, Pd, Ir, Rh, Tc, W, V). We found an adsorption-energy linear scaling relationship with positive slope between carbon monoxide (CO) and carboxyl (COOH) or hydrogen atom, but a weakly correlation with a negative slope for CO versus formate (HCOO) or CO versus hydroxyl (OH), which is attributed the beyond d-band-center model for the description of adsorption energies of HCOO and OH. And then, the selectivity of HCOOH dehydrogenation to HCOO (versus COOH) or COOH decomposition to CO2 (versus CO) on the Pt-based ordered alloys is regulated though breaking the adsorption-energy linear scaling relations of reaction intermediates. Our calculated results indicate that the L11-type CuPt is highly catalytic activity and selectivity toward formic acid decomposition and electrooxidation through the CO2 pathways of HCOOH→COOH+H→CO2+2H. This study underscores the importance of the unique adsorption-energy relations among reaction intermediates (e.g., CO versus OH) for screening high effective catalysts for hydrogen production of formic acid.

Magnetic Co/Fe nanocomposites derived from ferric sludge as an efficient peroxymonosulfate catalyst for ciprofloxacin degradation

• Cobalt adsorbed on ferric sludge was recycled to create bimetallic catalyst via a facile solvothermal method. • Co/Fe nanocomposites derived from ferric sludge (CoFe@FS) exhibited an excellent performance toward PMS. • SO 4 •− , • OH, O 2 •− and 1 O 2 were produced from PMS activation by synergetic effect of Co and Fe on the catalyst surface. • The possible degradation mechanism of CIP is proposed based on DFT calculations and LC/MS analyses. • This is a cost-effective method to achieve “treating wastewater by waste residuals”. Ferric sludge, generated during drinking water purification process, can be considered as a promising support with potential iron resource. Herein, magnetic bimetallic Co/Fe nanocomposite derived from ferric sludge (CoFe@FS) was created via a facile solvothermal treatment and employed as an efficient peroxymonosulfate (PMS) activator for the elimination of antibiotic ciprofloxacin (CIP) in water. CoFe@FS exhibited nano-sphere structure with the composites of CoO, CoFe 2 O 4 and SiO 2 crystals and presented excellent catalytic performance with 97.3% removal efficiency of 10 mg/L CIP within 15 min. Sulfate radicals (SO 4 •− ), hydroxyl radicals ( • OH) superoxide radicals (O 2 •− ) and singlet oxygen ( 1 O 2 ) all contributed to CIP degradation, and SO 4 •− functioned as the dominant reactive species in this activation system. CoFe@FS composite exhibited great reusability due to the strong Co/Fe-Si interaction and was able to regenerate by a simple solvothermal process. The CIP degradation mechanism in the CoFe@FS/PMS system were also proposed based on density functional theory (DFT) calculations and analysis of intermediate products. Overall, the magnetic Co/Fe bimetallic catalyst derived from ferric sludge could be employed as high-efficiency and low-cost candidate for the degradation of refractory organic contaminants. This work not only provides a promising reclamation strategy of water treatment waste from ferric sludge to high-effective catalyst, but also clarifies the mechanisms of PMS activation and CIP degradation. The more stable bimetallic CoFe catalysts derived from waste sludge need to be developed in the future study to relieve the occurrence of metal leaching.

Ionic liquid-functional MCM-41 as a high effective catalyst for the synthesis of isatylidene malononitrile via Knoevenagel condensation

Ionic liquid functional MCM-41 was synthesized, characterized and used as heterogeneous catalyst for the Knoevenagel condensation of isatins with malononitrile. A series of corresponding isatylidene malononitrile were obtained in high isolated yield (96–99%) at room temperature in a short time. The heterogeneous catalyst can be easily recovered by centrifugation and showed almost no loss of activity over 10 recycle experiments. At the same time, the gram-scale experiments showed excellent yields and provided a highly effective method for scale up applications.

Exploring degradation mechanism of tetracycline via high-effective peroxymonosulfate catalysts of montmorillonite hybridized CoFe composites and safety assessment

High-effective catalyst for activating peroxymonosulfate (PMS) to degrade pollutant in wastewater and minimize its toxicity is crucial. Herein, CoFe2O4/montmorillonite composites (CF/MO) were synthesized and used as high-effective PMS catalysts for the degradation of tetracycline (TC). The CoFe2O4 nanoparticles were firmly loaded on the surface of MO with FeOAl bonds, preventing the leaching of metal ions and bringing superior reusability and stability. It was optimized that the 20%-CF/MO showed superior catalytic activity to activate PMS for TC degradation, and SO4− was the dominant active species for TC complete degradation within 30 min and achieved high kinetic rate of 0.178 min−1. The ultrahigh catalytic performance toward TC degradation was ascribed to the cycles and regeneration of Co(III)/Co(II) and Fe(III)/Fe(II) synthergetic surface redox couples in the catalysts. The TC degradation pathway and reaction mechanism in the 20%-CF/MO/PMS system were also proposed based on DFT calculation. The ecotoxicity of degradation products was assessed using proteomics, and the toxicity of TC was found to decrease significantly as the reaction progressed.

Biodiesel production using low cost material as high effective catalyst in a microreactor

Given the scarceness of fossil fuels and high volume of pollution caused through the consumption of these fuels, many efforts are being made to produce alternative fuels. Biodiesel is one of the alternatives to diesel fuels. The main problem with biodiesel production is higher operation costs, as compared with diesel fuels. In this study, waste cooking oil and cow bone as the catalyst were used to reduce feed costs as much as possible. Moreover, a microreactor was utilized to reduce the residence time to 1 min. Using Box-Behnken design method, the effect of different variables including catalyst concentration (calcined cow bone), oil to methanol volume ratio, residence time, and reaction temperature on the purity of produced biodiesel were examined. The results showed that when using a catalyst concentration of 8.5 wt %, an oil to methanol volume ratio of 2.25 vol: vol, a residence time of 60 s, and a temperature of 63.1 °C, the maximum purity of biodiesel was 99.24%.

Polypyrrole/sewage sludge carbon as low-cost and high-effective catalyst for enhancing hexavalent chromium reduction and bio-power generation in dual chamber microbial fuel cells

Microbial fuel cell, a potential bio-electrochemical energy transducer can extract the bio-energy from wastewater by the consumption of the electro-active microorganism adhered the surface of anode, and the MFC performance is greatly inhibited by the cathode catalysts. Herein, polypyrrole/sewage sludge carbon electrode is fabricated by an electro-polymerization loading method and the electrode is employed as the cathode electrode in MFC for the removal of Cr(VI) and bio-energy release at the same time. The electrochemical analysis finds the polypyrrole/sewage sludge carbon electrode exhibits the low charge transfer resistance and Tafel slope, which can demonstrate that the polypyrrole/sewage sludge carbon electrode possesses strong conductivity and excellent electrochemical activity. In addition, Cr(VI) in the cathode chamber of MFC with the polypyrrole/sewage sludge carbon electrode can be totally removed at 30 h. And the maximum output power and Cr(VI) reduction rate of MFCs are 760.7 mW m−2 and 2.16 g·m−3·h−3, which are 2.79 and 1.51 times higher than those of carbon cloth electrode (272.5 mW·m−2 and 1.43 g·m−3·h−3). Moreover, Cr(VI) can be removed and deposited on the electrode in the form of Cr(OH)3. And polypyrrole plays an electron shuttling role in reducing the internal resistance of MFC and enhancing electrochemical activity of the electrode for Cr(VI) reduction. Consequently, the polypyrrole/sewage sludge composite can achieve more stable Cr(VI) removal and power than those of sewage sludge carbon, polypyrrole, and carbon cloth electrodes, demonstrating an effective and low-cost catalyst for accelerating Cr(VI) reduction and strengthening bio-power production.

Controlled synthesis of bimetallic Prussian blue analogues to activate peroxymonosulfate for efficient bisphenol A degradation

Developing high-effective catalysts with tailored composition and structure has attracted extensive attention. In this work, a serious of shape-specific Fe/Co Prussian blue analogs (PBAs), including concave, core-shell and polygonal cubes were prepared by the one-step hydrothermal reaction, which were altered by adjusting the ratio of Fe/Co in the initial reaction system. The catalytic performance toward bisphenol A (BPA) degradation was significantly affected by the ultimate structure and Fe/Co composition. Benefiting from appropriate elemental proportions, unique elemental distribution (rich Co in the core and rich Fe in the shell) and high specific surface areas, the core-shell PBAs (CSPs) exhibits significantly higher peroxymonosulfate (PMS) activation performance toward bisphenol A (BPA) degradation (96 % of removal efficiency within 2 min). The stability of the CSPs catalyst test further indicates that the Fe shell can effectively protect and inhibit the leaching of cobalt ions. Electron paramagnetic resonance (EPR) and radical quenching experiments measurement exhibited that both SO4− and OH are the main active species in the degradation process. Our work expanded new ideas of designing novel PBAs with controllable shape and specific core-shell composition with excellent catalytic performance.

Immobilizing 1–3 nm Ag nanoparticles in reduced graphene oxide aerogel as a high-effective catalyst for reduction of nitroaromatic compounds

To improve catalytic performance and stability of Ag nanoparticles (Ag NPs), a facile ultrasonication-assisted chemical reduction method was developed to fabricate reduced graphene oxide (rGO) aerogels loaded with 1–3 nm Ag NPs under the normal temperature and pressure. The ultrasonication facilitated the dispersion of Ag(I) in the form of silver ammonia and anchored onto GO nanosheets. Ag(I) and GO were simultaneously reduced to Ag(0) immobilizing onto 3D rGO hydrogels within the heterogeneous liquid phase, and ultimately formed 3D rGO-Ag NPs aerogels. The 3D rGO-Ag NPs aerogels displayed superb catalytic performance for the reduction of nitrobenzene (NB), 1,3-dinitrobenzene (DNB) and 4-nitrophenol (NP) into aniline, 1,3-diaminobenzene and 4-aminophenol, respectively. The individual reduction rate Kobs for NB, DNB and NP were 0.168 h−1, 0.109 h−1 and 0.092 h−1, which were much higher than those of other Ag NPs-based materials. Moreover, the immobilization of 1–3 nm Ag NPs in 3D rGO-Ag NPs was stable during the whole reduction reaction without aggregation and leaching. The high stability of Ag NPs in 3D rGO-Ag NPs and superb performance on catalytic reduction of nitroaromatic compounds (NACs) could be concluded into ultrasonication influence in the preparation procedure and synergistic effect of Ag NPs and 3D rGO in the catalytic reduction process. The simple ultrasonication-assisted chemical reduction approach provided a scaled-up application prospect in catalytic reduction of NACs by metal nanoparticle catalysts.

Nickel nanoparticles inlaid in lignin-derived carbon as high effective catalyst for lignin depolymerization

Ni nanoparticles inlaid in lignin-derived carbon constructing the “inlaid type” Ni/C-I was reported to improve stability and adjust metal-support interaction of lignin hydrogenolysis catalyst. The Ni/C-I was further heat treated in air to prepare Ni/C-R so as to re-expose the blocked active sites by carbon species. A lot of characterization techniques were carried out to confirm the “inlaid structure” of the catalysts. The lignin depolymerization results demonstrated that the Ni/C-R had better catalytic performance than traditional “supported type” Ni/C, 23.3% aromatic monomer yield and 82.4% bio-oil yield were achieved. Moreover, the mechanism studies with lignin model compound revealed that Ni/C-R had better bond breaking ability than Ni/C, even CC bond could be cleaved. The electron effect could be responsible for that, since the electrons could transfer from Ni0 to carbon support for Ni/C-R, which could improve the bond breaking ability.

Synthesis and characterization of ES/Cu(OH)2 nanocomposite: a novel and high effective catalyst in the green synthesis of pyrano[4,3-b]pyrans.

The eggshell (ES) supported Cu(OH)2 nanoribbons containing 8 wt.% Cu(2+) as a novel and heterogeneous catalyst was synthesized by simply adding an aqueous solution of CuSO4 on the eggshell support at ambient temperature. The nanocomposite system was characterized by scanning electron microscopy (SEM), transition electron microscopy (TEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectroscopy and BET surface area analysis. Also, electrochemical impedance spectroscopy was used as powerful techniques for an electrical conductivity investigation. The loading of copper on the mesoporous supports provides high catalytic activity for the green synthesis of pyrano[4,3-b]pyrans. The reaction proceeds to completion in 5 min with excellent yields of 93-97%. The suggested strategy for synthesis of pyrano[4,3-b]pyrans is very interesting due to application of a green and low cost composite as a heterogeneous catalyst and its simplicity in preparation, short reaction time, high yields without further purification and high reusability without any loss of catalytic activity.

Mesoporous Au–TiO2 nanoparticle assemblies as efficient catalysts for the chemoselective reduction of nitro compounds

In this article, we demonstrate novel mesoporous Au-loaded TiO2 nanoparticle assemblies (Au–MTA) as high-effective catalysts for the selective transformation of nitroaromatics into the corresponding aryl amine products. These materials feature a three-dimensional open porous structure consisting of interconnected uniform gold and TiO2 nanoparticles, large internal surface area (ca. 104–120 m2 g−1), and narrow mesopores (ca. 7.3–7.6 nm). Au–MTA displays outstanding performance for the selective reduction of nitro into amine groups using sodium borohydride as a reducing agent under ambient conditions. We show that both chemoselectivity and hydrogenation activity of the Au–MTA catalysts are highly related to the Au loading and particle size. As a result the 2% Au–MTA associated with 5 nm sized Au particles was found to be a prominent catalyst for hydrogenation reactions, providing exceptionally high selectivity (>96%) and conversion yield (>92%) to the corresponding amines. The implication of these results is that mesoporous ensembles of gold and TiO2 nanoparticles should be considered for the synthesis of fine amine chemicals.
