电沉积法制备碱性电解水镍基析氧电极的研究进展
Research progress on nickel-based oxygen evolution electrode prepared by electrodeposition for alkaline water electrolysis
摘要
Abstract
Under the goal of"peak carbon dioxide emissions,carbon neutral",green hydrogen has become a promising clean energy source.The technology of producing green hydrogen by alkaline electrolysis of water has the highest degree of commercialization,but because of the slow kinetic process of oxygen evolution reaction(OER)and the high overpotential,it has become the main bottleneck restricting the efficiency of electrolytic water electrode.There is still much room to improve the OER performance of nickel mesh or nickel foam electrode widely used in commercial electrolytic cells.It is beneficial to improve the electrode efficiency and reduce the cost of hydrogen production by compounding nickel-based catalytic functional layer on it and developing new high-activity oxygen evolution electrode.Electrodeposition technology has the advantages of simple process and mild conditions,which is beneficial to scale up the production of self-supporting electrodes,and has become one of the ideal processes for industrial production of OER electrodes.In this paper,the research progress of nickel-based oxygen evolution electrode prepared by electrodeposition technology and used in alkaline electrolysis of water in recent years is reviewed.Nickel-based(hydrogen)oxides,bimetals,multi-metals and nonmetal-doped nickel-based catalysts are prepared on nickel mesh or nickel foam substrate by electrodeposition technology as catalytic functional layers.The OER performance of nickel-based self-supporting electrodes is improved by enhancing the conductivity of catalytic functional layers and the synergistic effect between metals,increasing the number of active sites,reducing the diffusion path and changing the surface atomic configuration.In addition,the application of nickel-based self-supporting electrode in water electrolysis field is clarified,and the challenges of electrodeposition method are pointed out.关键词
