PtCu-based alloy nanomaterials have shown great potential in methanol oxidation reaction (MOR) owing to the lower cost and good anti-poisoning ability. However, the dissolution of non-precious metal makes them suffer from severe stability issues, greatly impeding the practical application of direct methanol fuel cells. Herein, PtCuIr aerogels are successfully fabricated through a one-step NaBH4reduction strategy to anchor trace Ir on PtCu aerogels based on compositional engineering, which serves as advanced electrocatalysts to achieve enhanced ...
