Bimetallic PdAu Nanoframes for Electrochemical H₂O₂ Production in Acids

Electrochemical oxygen reduction reaction via the two-electron pathway to H2O2 represents a promising route to enable its on-site, on-demand production for direct consumer use. In particular, running this reaction in acids is practically relevant and scientifically challenging. Herein, we demonstrate that bimetallic PdAu nanoframes can be prepared via stepwise solution growth and etching under well-controlled conditions. The product exhibits a...
