Efficient solar-driven crude oil cleanup via graphene/cellulose aerogel with radial and centrosymmetric design

Frequent oil spills pose significant threats to ecosystems; therefore, strict requirements are needed for prompt remediation and reclamation of spilled oil. Influenced by the structure of coniferous trees and their water transport, this experiment used cellulose nanofiber (CNF), polyvinyl alcohol (PVA), and methyltrimethoxysilane (MTMS) to prepare radially centrosymmetric aerogels. By utilizing the in-situ polycondensation reaction of MTMS, CNF, and PVA were connected, and the hydrophobicity and mechanical properties of the aerogel were greatly enhanced. Furthermore, the introduction of graphene oxide (GO), enshrouded within the cross-linked network, engenders heightened photo-thermal effects. The resultant composite aerogel exhibits expeditious oil absorption under solar irradiation and radial layered channel architecture, significantly curtailing the crude oil absorption timeframe (achieving a maximum absorption capacity of 51.7 g/g). Moreover, it demonstrates superior performance in rapidly and repeatedly adsorbing highly viscous crude oil, surpassing existing literature. Notably, continuous absorption of high-viscosity crude oil is achieved by integrating the composite aerogel with a peristaltic pump. This study offers a novel approach to the absorption and retrieval of high-viscosity crude oil, broadening the potential application horizons of CNF-based aerogels within environmental remediation.

Femtosecond laser structured black superhydrophobic cork for efficient solar-driven cleanup of crude oil

Marine oil spills have become a major global environmental challenge, yet there remains a lack of effective and environmentally friendly strategies for the remediation of water contaminated with high-viscosity oil. In this study, we introduce a superhydrophobic oleophilic material with photothermal properties for efficient absorption of viscous oil. Femtosecond laser treatment methodology is applied to cork (FSLA-cork), which exhibits not only superior hydrophobic and oleophilic properties but also the exceptional ability to be rapidly heated from ambient conditions to 58 °C in 10 s under 1.8 solar irradiation. Under solar irradiance, the FSLA-cork adsorbent functions synergistically by capillary absorption and centrifugal pumping. At one-sun intensity, an oil absorption rate of 4.02 g cm−2 within 200 s was observed. The high adsorption rates of FSLA-cork combined with the high availability of the raw material and its eco-friendly fabrication methods indicate that such methods and materials can be utilized for large-scale clean up of aqueous environments contaminated with high-viscosity oils.

Construction of superhydrophobic flexible polyurethane with dual nano-enhancement effect for solar-assisted high-viscosity oil cleanup and oil-water separation

Rapid and safe implementation of viscous crude oil cleanup is still a daunting challenge. Superhydrophobic materials are outstanding candidates for handling solvent spills, but are limited to recovering low viscosity oil and organic solvents. Hence, a polyurethane foam (PMRP-PU) integrating superelasticity, dual solar-responsive and fire resistance was fabricated by blending MXene and reduced graphene oxide (RGO) via self-foaming method. The surface temperature of the PMRP-PU reached 105 °C after simulated sunlight irradiation for 600 s. PMRP-PU had outstanding adsorption performance for low-viscosity oil and organic solvent (∼70.1 g/g) at room temperature, and the adsorption capacity of high-viscosity oil was also increased by 202.1 % compared with pure PU. Additionally, the adsorption capacity of PMRP-PU-3 remained at 92.7 % of the original level after 20 cycles of experiments. Excellent acid and alkali resistance and high temperature stability also greatly improved the environmental adaptability of the foam. Contrary to the flammability of pure PU, the peak heat release rate and total heat release of PMRP-PU-3 were decreased by 22.6 % and 25.2 %, respectively, and the melt dripping phenomenon disappeared during burning, exhibiting excellent fire safety. Briefly, this polyurethane foam can be repeatedly used for oil spill cleaning, and has a broad development prospect in the field of oil-water separation.

Superhydrophilic carbon@halloysite nanotube decorated sponge composites for high efficiency solar steam generation and cleanup of crude oil

Three dimensional composite evaporators have now widely been used for solar driven steam generation. However, some issues such as weak interfacial interaction, moderate water transport ability and salt precipitation should be addressed for high efficiency solar driven interface evaporation. Here, carbon modified halloysite nanotubes (CHTs) are firmly anchored onto the skeleton of Polyvinyl alcohol (PVA) sponges for preparation of compressible and superhydrophilic CHTs/PVA evaporators (CPEs). CHTs endow the evaporator with outstanding light absorption and photothermal conversion performance. In addition, the hierarchically porous and hollow structures inside CPEs ensure the evaporator powerful water transport capability and hence excellent salt rejection behavior. Benefiting from the strong interfacial interaction between CHTs and the PVA sponge, CPEs possess superior surface stability and durability. The synergy of the solar driven interface evaporation and natural evaporation from the side walls contributes to a high evaporation rate (up to 3.49 kg m−2 h−1). The evaporation rate is maintained when CPE is mechanically compressed. Also, the sponge composite can be used for cleanup of crude oil, based on the photothermally induced decrease of oil viscosity. This study can provide inspiration to develop solar evaporators for high performance desalination and water purification.

Coupling Carbon-Based Composite Phase Change Materials with a Polyurethane Sponge for Sustained and Efficient Solar-Driven Cleanup of Viscous Crude Oil Spill.

The efficient cleanup of crude oil spills is a worldwide problem due to their high viscosity and low fluidity. Under the assistance of solar radiation, adsorbents with in situ heating function are becoming the ideal candidates to solve this problem. In this study, a new strategy coupling a polyurethane (PU) sponge with phase change materials (PCMs) is proposed to realize the efficient utilization of solar energy and crude oil cleanup. Wormlike carbon nanotubes/mesoporous carbon (CNTs/MC) with a core-shell structure was used to encapsulate polyethylene glycol (PEG), which was then introduced into the PU sponge for photothermal conversion and thermal storage. After coating with a polydimethylsiloxane (PDMS) layer, the sponge was further endowed with hydrophobic characteristics. Additionally, PDMS can function as a binder between PEG@CNTs/MC and sponge skeleton. The resulting PEG@CNTs/MC/PU/PDMS (named as PEG@CMPP) exhibited excellent photothermal conversion and high absorption capacity for high-viscosity crude oil. Most importantly, thanks to the heat storage properties of PEG, the stored heat can be sustainably transferred to the surrounding crude oil to promote its continuous absorption even under insufficient light intensity conditions. The crude oil absorption capacity of PEG@CMPP-3 reached approximately 0.96 g/cm3 even after the light source was removed, which manifested the distinctive advantages compared to the conventional photothermal adsorbent. The proposed approach integrates the high efficiency of solar-assisted heating and energy-conserving advantage, thereby providing a feasible strategy for highly efficient remediation of viscous crude oil spills.

High-efficiency and all-weather crude oil spill remediation by an eco-friendly self-heating MXene-coated poly(butylene adipate-co-terephthalate) porous monolith

Frequent oil spill incidents have resulted in serious environmental pollution posing a great threat to human health and ecological system, thus developing new absorbents to efficiently remove and recycle high-viscosity crude oil is attracting more attention. We herein report an eco-friendly flexible poly(butylene adipate-co-terephthalate) (PBAT)-based monolith with MXene (Ti3C2Tx) and polydimethylsiloxane (PDMS) coatings (P-MXene@PBAT monolith) by convenient and economical preparation method for self-heating driven fast crude oil cleanup. Due to unique three-dimensional interconnected pore structure and superior hydrophobicity, the P-MXene@PBAT showed high saturated absorption capacity and cyclic separation efficiency for multifarious low-viscosity oils. The P-MXene@PBAT was endowed with excellent photo/electro-thermal performance via wrapping MXene layer. The maximum surface temperature of monolith quickly reached up to 81 °C under 1.0 kW m−2 (1.0 sun) irradiation and 91 °C under 8 V voltage, respectively. Furthermore, the P-MXene@PBAT could self-heat crude oil to dramatically decrease oil viscosity and accelerate separation process. Specially, the P-MXene@PBAT was able to continuously separate crude oil from water with a simple pump-assisted absorption device (crude oil flux of 204 kg m−2 h−1), which adapted to varied working conditions by coupling solar heating and Joule heating. Such environmental-friendly all-weather absorbent design provides a sustainable strategy for efficient remediation of crude oil spill.

Green fabrication of durable foam composites with asymmetric wettability by an emulsion spray-coating method for photothermally induced crude oil cleanup

Chemical spills, especially oil spills, are becoming an increasingly serious environmental issue. It remains a challenge to develop green techniques to prepare mechanically robust oil–water separation materials, especially those capable of separating high-viscosity crude oils. Herein, we propose an environmentally friendly emulsion spray-coating method to fabricate durable foam composites with asymmetric wettability for oil–water separation. After the emulsion, composed of acidified carbon nanotubes (ACNTs), polydimethylsiloxane (PDMS) and its curing agent, is sprayed onto melamine foam (MF), water in the emulsion is first evaporated, while PDMS and ACNTs are finally deposited on the foam skeleton. The foam composite exhibits gradient wettability and turns from superhydrophobicity of the top surface (the water contact angle reaches as high as 155.2°) to hydrophilicity of the interior region. The foam composite can be used for the separation of oils with different densities and has a 97% separation efficiency for chloroform. In particular, the photothermal conversion-induced temperature rise can reduce the oil viscosity and complete the high-efficiency cleanup of crude oil. This emulsion spray-coating technique and asymmetric wettability show promise for the green and low-cost fabrication of high-performance oil/water separation materials.

Biodegradation of asphaltene by lipopeptide-biosurfactant producing hydrocarbonoclastic, crude oil degrading Bacillus spp.

Asphaltene is the most recalcitrant compound in crude oil. Bacteria were isolated from crude oil contaminated soil and their efficiency for hydrocarbon degradation was determined using GC–MS and isolates were screened for biosurfactant production using FT-IR. Two Bacillus spp. having hydrocarbonoclastic and lipo-peptide biosurfactant-producing abilities were experimented for their asphaltene removal potential through oil removal efficiency (ORE%) and asphaltene degradation efficiency (ADE%). B. thuringeinsis SSL1 and B. cereus SSL3 could degrade 76.4% and 67.4% of asphaltene (20 g L−1), in vitro, respectively, which is much higher than previous reports. B. thuringiensis SSL1 is recommended for effective breakdown of asphaltene, total petroleum hydrocarbon, and polyaromatic hydrocarbon degradation, aided by its biosurfactants, which is useful for crude oil cleanup. Biosurfactants are important for enhancing the availability of hydrophobic hydrocarbons to bacteria, which is beneficial for efficient crude oil remediation. These findings could lead to more effective strategies for complete clean-up of crude oil pollution.

Facile fabrication of solar-heating and Joule-heating hyperelastic MXene-modified sponge for fast all-weather clean-up of viscous crude oil spill

Developing rational sorbent for viscous crude oil clean-up is still a daunting challenge, which requires rapid oil-uptake capability and scalable fabrication process. Herein, a heatable hydrophobic sponge sorbent (H-MXene/PVA/MS) with excellent light/Joule-heating performances was fabricated by a simple and feasible top-down approach. MXene nanosheets firmly coated on the substrate skeleton gave the sorbent outstanding ability to convert solar/electricity into heat rapidly due to the localized surface plasmon resonance (LSPR) effect and ultrahigh metallic conductivity. The surface temperature of H-MXene/PVA/MS could reach about 80 ℃ under 1.0 sun irradiation within 30 s and 125 ℃ under a low applying voltage of 6 V within 25 s. The rapid and sufficient heat generation on the sorbent would effectively warm the surrounding oil and accelerate its absorption. The oil absorption rate under 1.0 sun irradiation (1 kW/m2) improved about 41.5 times compared to the unheated sorbent. Moreover, the sorbent showed practical application potential in harsh environments due to its high coating firmness, durability, elasticity, and suitability for large-scale production and operations. Thus, the easily-prepared H-MXene/PVA/MS sorbent, which mainly focuses on solar-heating, supplemented by Joule-heating, provides an efficient and energy-efficient strategy for addressing large-scale viscous oil spill clean-up.

Photothermal and Concus Finn capillary assisted superhydrophobic fibrous network enabling instant viscous oil transport for crude oil cleanup.

Rapid and effective removal of highly viscous oil spills from the sea remains a great challenge globally. Superhydrophobic materials are attractive candidates for handling oil spills, but they are restrained to recover oils with low viscosity exclusively. Herein, we report a novel polypyrrole wrapped superhydrophobic fibrous network using cross-shaped polyester fibers as starting blocks. The polypyrrole coating enables the absorbent to convert light to heat, ensuring that the viscosity of heavy oils in the proximity can be easily controlled. In the meanwhile, the special structure of the starting fibers initiates Concus Finn (CFin) capillary allowing instant oil transport in the network. When the absorbent is exposed to light oils (0-500 mPa.s), the oils can be transported instantly via CFin capillary. Interestingly, under synergistic effect of light-to-heat conversion and CFin capillary, a drawing-sticking crude oil strip (105 mPa.s) is sucked instantly against gravity by the absorbent. The absorbent is successfully applied to efficiently separate both oil/water mixtures and oil/water emulsions (efficiency > 99%). Such absorbent can absorb 62.99-74.23g/g light oils on average and up to 123.3g/g crude oil under 0-2 sun illumination, holding a huge potential in managing oil spills.

Biobased Castor Oil-Based Polyurethane Foams Grafted with Octadecylsilane-Modified Diatomite for Use as Eco-Friendly and Low-Cost Sorbents for Crude Oil Clean-Up Applications.

Herein we report the synthesis and characterization of novel castor oil-based polyurethane (PU) foam functionalized with octadecyltrichlorosilane (C18)-modified diatomaceous earth (DE) particles, exhibiting superior hydrophobicity and oil adsorption, and poor water absorption, for use in effective clean-up of crude oil spillage in water bodies. High-performance and low-cost sorbents have a tremendous attraction in oil spill clean-up applications. Recent studies have focused on the use of castor oil as a significant polyol that can be used as a biodegradable and eco-friendly raw material for the synthesis of PU. However, biobased in-house synthesis of foam modified with C18-DE particles has not yet been reported. This study involves the synthesis of PU using castor oil, further modification of castor oil-based PU using C18 silane, characterization studies and elucidation of oil adsorption capacity. The FTIR analysis confirmed the fusion of C18 silane particles inside the PU skeleton by adding the new functional group, and the XRD study signified the inclusion of crystalline peaks in amorphous pristine PU foam owing to the silane cross-link structure. Thermogravimetric analysis indicated improvement in thermal stability and high residual content after chemical modification with alkyl chain moieties. The SEM and EDX analyses showed the surface's roughness and the incorporation of inorganic and organic elements into pristine PU foam. The contact angle analysis showed increased hydrophobicity of the modified PU foams treated with C18-DE particles. The oil absorption studies showed that the C18-DE-modified PU foam, in comparison with the unmodified one, exhibited a 2.91-fold increase in the oil adsorption capacity and a 3.44-fold decrease in the water absorbing nature. From these studies, it is understood that this novel foam can be considered as a potential candidate for cleaning up oil spillage on water bodies.

Synthesis of elastic hydrophobic biomass sponge for rapid solar-driven viscous crude-oil cleanup absorption, oil-water separation and organic pollutants treating

Oil spills pose a global challenge for environmental remediation and the high viscosity of crude oil makes conventional sorbents ineffective for complete remediation. Inspired by the solar energy-motivated viscosity-break, a photothermal three-dimensional (3D) polydimethylsiloxane modified CuS-loaded biomass-derived carbon fibers/reduced graphene sponge (PDMS/CuS/CFs/RGO) was synthesized using self-assembly, carbonization, freeze-drying, and hydrophobic modification methods that utilize natural renewable resources in an efficient manner. By using infrared thermal imaging, oil droplet permeability behavior, and oil absorption-recovery, we studied the photothermal effect of adsorbents on oil absorption. Based on the results, the PDMS/CuS/CFs/RGO sponge demonstrated excellent photothermal conversion ability and stability with almost full solar absorption. Under 0.3-sun simulated irradiation (0.3 kW/m2) at room temperature, the surface temperature spontaneously increased to 75.9 °C, which reduced the in-situ viscosity of crude oil and significantly increased its diffusion coefficient and adsorption rate. Consequently, the PDMS/CuS/CFs/RGO sponge exhibited excellent oil cleaning absorption rates up to 66.8 times their weight and outstanding recyclability. Additionally, the sponge showed excellent adsorption capabilities for organic solvents and low viscosity oils (13.8–26.1 g/g). Notably, the PDMS/CuS/CFs/RGO sponge was able to achieve dye degradation due to its photocatalytic property. Combined with comprehensive functions including rapid solar-driven viscous crude-oil cleanup absorption, oil/water separation, and photocatalytic property, the bio-based PDMS/CuS/CFs/RGO sponge has great application prospects in water remediation, especially in the treatment of contaminated water with complex components.

Durable superhydrophobic sponge for all-weather cleanup of viscous crude oil by electrothermal and photothermal effects

Creating innovative absorbent materials with a rapid absorption rate and high absorption efficiency for viscous crude oils continues to be a global problem. Hydrophobic/oleophilic porous sorbents with light-to-heat or electric-to-heat capabilities are attractive options for crude oil clean-up, but their complicated preparation processes, poor stability, and variable weather restrict their practical usage. Herein, the light-absorbing and electrical polypyrrole and Fe3O4 are introduced to endow the melamine sponge with excellent photothermal and electrothermal properties, while the polydimethylsiloxane is coated on the surface of the sponge to make it durable, compressible, and superhydrophobic. Thanks to the superior photo/electro-heat conversion capability, the temperature of the as-prepared sponge′s surface may reach 95.9 °C under solar light with 1 kW m−2 intensity or 101.4 °C under a voltage of 11 V, making it adaptable to reduce the crude oil’s viscosity and absorb it in all weather. In addition, when the sponge is exposed to sunlight and voltage at the same time, its crude oil absorption velocity is dramatically improved and is about 107 times greater than that of an unheated sponge. Based on the eco-friendly preparation method and excellent crude oil absorption performance, this work provides a promising absorbent for the recycling of spilled crude oil.

Superhydrophobic PDMS@GSH wood with Joule heat and photothermal effect for viscous crude oil removal

Recently, the membrane separation materials show promising applications in the fields of crude oil removal because of their low energy consumption and less secondary pollution. However, the membrane separation materials suffer problem of low separation efficiency due to the high viscosity of crude oil. Here, a superhydrophobic material with Joule heat and photothermal effect was prepared by decorating the delignified wood with reduced graphene oxide (GSH) and vinyl terminated polydimethylsiloxane (V-PDMS) through thiol-ene click reaction. The prepared PDMS@GSH wood exhibited stable superhydrophobicity with a water contact angle of 156°. Meanwhile, the GSH layer provided promising electrothermal effect that endowed the PDMS@GSH wood with excellent crude oil/water separation capability under the Joule heat with a surface temperature of 139 °C and separation rate of 1.78 × 105 kg m−3 h−1. Besides, the PDMS@GSH wood displayed a good photothermal effect that assisted with the Joule heat to heat the wood for crude oil removal to save energy. More importantly, the PDMS was crosslinked with GSH on the wood via thiol-ene click reaction, leading to the stable superhydrophobicity and electrical conductivity in strong acid or alkali environment. This material has broad application prospects in crude oil clean-up due to its high separation speed and easy large-scale production.

Robust multifunctional rGO/MXene@PPS fibrous membrane for harsh environmental applications

Efficient cleanup of crude oil spills and wastewater treatment in harsh conditions remains a big challenge due to the absent of robust membrane materials. Herein, a kind of reduced graphene oxide and MXene (Ti3C2Tx) decorated PPS fibrous membrane with super chemical-resistance for all-weather cleanup of crude oil via Joule heat and solar-driven heat performance was reported. With the assist of the Joule heat and photothermal effect, the crude oil adsorption rate of composite membrane improved by more than 97 %. More importantly, the robust membrane still remained excellent oil/water separation performance even under strong acid and alkali conditions. Meanwhile, the gravity driven oil (dichloromethane)/water separation flux of composite membrane reached 11,502 L m-2h−1 with a separation efficiency up to 99.98 %. Moreover, the composite membrane could realize solar-driven evaporation for seawater desalination due to its great photothermal properties, the evaporation rate could be up to 1.235 kg m-2h−1 under one sun. The composite membrane also exhibited great electrical conductivity and EMI shielding performance for radiation protection with efficiency of 61.9 dB. This robust multifunctional fibrous membrane design offers a progressive approach for the efficient cleanup of viscous crude oil spills, oil/water separation, solar desalination and EMI shielding under harsh environments.

Solar-assisted self-heating Ti3C2Tx-decorated wood aerogel for adsorption and recovery of highly viscous crude oil

Frequent oil-spill accidents have posed serious threats to ecosystem balance and the efficiency of resources use. Hydrophobic adsorbents that can adsorb and recover oil without causing secondary pollution are ideal candidates for the remediation of oil contamination in water. However, these composites are inefficient for crude oil-spills cleanup because crude oil has low liquidity of at room temperature. Increasing the temperature can effectively enhance the flowability of crude oil. To achieve efficient crude-oil heating and removal in situ, wood aerogels were immersed in Ti3C2Tx suspensions and then coated with polydimethylsiloxane (PDMS) to obtain a solar-heated adsorbent (PT-WA). The prepared PT-WA exhibits super-hydrophobicity (water contact angle: 154° ± 2°), mechanical robustness (withstanding 20 loading-unloading cycles under 50% strain without structural damage), strong solar absorption, and favorable photothermal-conversion capability (rising to ~85 °C within 90 s under 1.5 sun). Owing to these advantages, PT-WA is an effective adsorbent for crude oil cleanup. In addition, a ‘self-heating crude oil collector’ was assembled for the fast adsorption and restoration of crude oil from the water surface. This solar-assisted self-heating sorbent offers a competitive platform for the cleanup and recycling of viscous crude oil spills.

Solar-assisted high-efficient cleanup of viscous crude oil spill using an ink-modified plant fiber sponge

Rapid and efficient clean-up of viscous crude oil spills is still a global challenge due to its high viscous and poor flowability at room temperature. The hydrophobic/oleophilic absorbents with three-dimensional porous structure have been considered as a promising candidate to handle oil spills. However, they still have limited application in recovering the high viscous oil. Inspired by the viscosity of crude oil depended on the temperature, a solar-heated ink modified plant fiber sponge (PFS@GC) is fabricated via a simple and environmentally friendly physical foaming strategy combined with in-situ ink coating treatment. After wrapping by the polydimethylsiloxane (PDMS), the modified PFS@GC (PFS@GC@PDMS) exhibits excellent compressibility, high hydrophobic (141° in water contact angle), solar absorption (> 96.0%), and oil absorptive capacity (12.0–27.8 g/g). Benefiting from the favorable mechanical property and photothermal conversion capacity, PFS@GC@PDMS is demonstrated as a high-performance absorbent for crude oil clean-up and recovery. In addition, PFS@GC@PDMS can also be applied in a continuous absorption system for uninterrupted recovering of oil spills on the water surface. The proposed solar-heated absorbent design provides a new opportunity for exploring biomass in addressing large-scale oil spill disasters.
