Project Description:  The production of H2O2 via the direct synthesis process (H2 + O2 → H2O2) could result in a significant decrease in production costs, while also reducing the environmental impacts. Palladium has been demonstrated as being an excellent catalyst for the direct synthesis of H2O2. An emerging class of bimetallic catalysts are Single Atom Alloy (SAA) catalysts in which the reactive metal (e.g., Pd, Pt) exists as isolated single atoms in a matrix of unreactive metal (e.g., Au, Ag, Cu, Ni, etc.). These are known to significantly modify the chemical, geometric and electronic properties of the active metal and provide opportunities to escape linear free energy scaling relationships. By performing rate measurements, infrared spectroscopy, X-ray absorption spectroscopy, isotope exchange experiments and a variety of other material characterization techniques, we aim to establish a clear understanding of the effects of single atom alloy catalysts on the kinetics and mechanism of the direct synthesis of H2O2.
