Synthesis of Cu-Pd nanoplates and their catalytic performance for H₂O₂ generation reaction

We reported on an aqueous-phase synthesis of copper-palladium (Cu-Pd) nanoplates consisting of 5 nm-sized Pd nanoparticles deposited on Cu nanoplates. In the present synthesis, ascorbic acid was used as a reducing agent to prevent galvanic replacement. By controlling the experimental conditions, we could control the weight percent of Pd in the nanoplates from 0.56% to 2.02%. The Cu-Pd nanoplates with Pd content of 2.02% exhibited high catalytic performance in the direct H₂O₂ generation reaction.
