Abstract

The introduction of small quantities of Pt into supported AuPd nanoparticles is found to result in enhanced catalytic efficiency in the direct synthesis of H2O2. This is attributed to a combination of superior H2O2 synthesis rates, as determined through calculation of initial rates of reaction, and an inhibition of H2O2 degradation pathways, achieved through the modification of Pd oxidation states. Through gas replacement experiments we demonstrate that it is possible to reach concentrations of H2O2 approaching those produced during initial stages of the current industrial means of H2O2 production.
