Abstract
Abstract The electrochemical synthesis of hydrogen peroxide (H2O2) represents a promising alternative to the anthraquinone process, as it combines on-site chemical and electrical production. The design of selective electrocatalysts is challenging and is commonly based on the alloying of elements to generate a synergistic effects and increase activity. In the present work, we report the electrochemical activity of Au-Pd nanoparticles immobilized directly onto an electrode as a model to study {H2O2} electrochemical synthesis from fundamentals to continuous production. The impact of composition on the oxygen reduction (ORR), on the selectivity, as well as the peroxide reduction and oxidation (PROR) are studied.
