Abstract

Kinetics of hydrogen peroxide decomposition over Pd/SiO₂ catalyst was investigated as part of a larger project to determine the overall kinetics of hydrogen peroxide formation by Pd/SiO₂ catalyzed direct combination of hydrogen and oxygen. A Pd oxidative/reductive cycle mechanism for the decomposition of H₂O₂ over Pd/ SiO₂ was proposed. A Rideal-Eley rate expression based on this mechanism was shown to accurately correlate experimental data over a wide range of H₂O ₂ concentration and temperature. This rate equation was shown to also apply in the presence of stabilizing concentrations of H₂SO ₄.
