Application of Metal-perovskite Oxide Thin Film Prepared by Magnetron Sputtering in Water Splitting
Currently,the production of zero emission energy carrier,hydrogen,by electrocatalytic water splitting is a hot research topic.The perovskite oxide is one of the most promising candidate substituting noble metal catalyst,because of its earth abundance and low price.In this work,magnetron sputtering technology and in-situ exsolution method were used to prepare metal-oxide heterostructure as a potential oxygen evolution catalyst.It was found that the in-situ exsolution method could enhance the electrochemical surface area,activity and stability.This work provides a new design thinking for low cost water splitting catalysts.
