摘要

With exhaustion of fossil fuels and the deterioration of global environment,widespread and intensive researches have been concentrated on clean and sustainable alternative energy sources,such as metal-air batteries [1],fuel cells [2] and water splitting devices [3].Electrocatalytic oxidation of water to O2 (oxygen evolution reaction,OER) is a vital chemical process involved in energy storage and conversion from renewable sources in form of molecular fuels such as H2 via water electrolysis,which has attracted a great amount of research efforts in the past few years [4,5].Nowadays,RuO2 and IrO2 are widely used as typical excellent OER electrocatalysts.However,their high-cost and scarce nature restricts the broadly commercial application of those materials [6,7].Hence,there is an urgent demand to develop low cost,highly efficient,and superb stable OER catalysts.
