Effect of Selectivity Enhancers on the Structure of Palladium during High-Pressure Continuous-Flow Direct Synthesis of Hydrogen Peroxide in Ethanol

A potentially green process to produce hydrogen peroxide (H2O2) is its direct synthesis from molecular hydrogen and oxygen. Still, the lack of mechanistic understanding of the reaction impedes a knowledge-based catalyst design for improved selectivity and stability. In this study, we employed X-ray absorption spectroscopy (XAS) to obtain structural information on a titania-supported palladium (Pd) catalyst under H2O2 synthesis conditions. The...
