Abstract

The electrochemical oxidation of H2 is > 100 times slower in alkaline electroltyes in comparison to acidic electrolytes. Here, we report that ordered intermetallic PtSb is a potent catalyst for the alkaline hydrogen oxidation reaction. PtSb exhibits higher activity and lower cost than Pt, demonstrating that it is a promising anode catalyst for alkaline fuel cells.
