One-pot synthesis of cubic PtCu 3 nanocages with enhanced electrocatalytic activity for the methanol oxidation reaction

Noble metals such as platinum (Pt) are widely used as catalysts in fuel cells and other heterogeneous catalytic processes. However, there is an urgent need to develop substitutes for pure Pt catalysts to reduce the overall use of precious Pt and at the same time to enhance poisoning resistance. A pr...
