Kinetically controlled synthesis of AuPt bi-metallic aerogels and their enhanced electrocatalytic performances

Abstract

Recently, metallic hydrogels/aerogels have received tremendous attention due to their unique physical and chemical properties. For the first time, we reported the successful synthesis of AuPtx metallic hydrogels at 60 °C in 2-4 h. Surfactant-free AuPt5 metallic hydrogels displayed enhanced electrocatalytic activities and stabilities toward methanol oxidation.
