摘要
Electrolytic water is considered to be the first choice for large-scale industrial hydrogen production in the future due to its good matching with wind power,photovoltaic and other renewable energy power generation systems[1].In recent years,the emerging proton exchange membrane(PEM)water electrolysis for hydrogen production(Fig.1(a))has gradually become the mainstream development direction due to its advantages such as fast start and stop,high working current density(greater than 1 A.cm^(-2)),small size of electrolytic cell,and good matching with renewable electric energy.However,in acidic electrolytes,the ki-netics of oxygen evolution reaction(OER)half-reaction is very slow.In addition,the lower commercial value of anode O_(2)further reduces the economic benefits of traditional PEM technology.Therefore,from the perspective of reducing energy consumption and improving economic benefits,finding a more dynamic and/or thermodynamic OER alternative oxidation reaction has become the key to promote the practical appli-cation of hydrogen production by electrolytic water[2].
