Abstract:The hydrogen production from water electrolysis is of interest as a renewable energy generation technology. However, the high price of noble platinum (Pt) catalysts for the hydrogen evolution reaction (HER) is a big challenge to use it. Herein, we fabricate cost-effective CoPt bimetallic alloys and explore the effect of Co composition on the electrochemical behavior of such alloys, which has been rarely reported. A series of Co1-xPtx (x = 0.25; 0.5; 0.75) alloys are prepared via a room-temperature chemical red… Show more
