Kinetics and Mechanism of Decomposition of Hydrogen Peroxide over Pd/SiO2 Catalyst Yury Voloshin, James Manganaro and Adeniyi Lawal / Yury Voloshin in Industrial & engineering chemistry research, Vol. 47 n°21 (Novembre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 n°21 (Novembre 2008) . - p. 8119–8125 Titre : Kinetics and Mechanism of Decomposition of Hydrogen Peroxide over Pd/SiO2 Catalyst Yury Voloshin, James Manganaro and Adeniyi Lawal Type de document : texte imprimé Auteurs : Yury Voloshin, Auteur ; James Manganaro, Auteur ; Adeniyi Lawal, Auteur Année de publication : 2008 Article en page(s) : p. 8119–8125 Note générale : Chemical engineering Langues : Anglais (eng) Résumé : 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 H2O2 concentration and temperature. This rate equation was shown to also apply in the presence of stabilizing concentrations of H2SO4.
