Efficient hydrogen peroxide decomposition on bimetallic Pt–Pd surfaces (original) (raw)

Hydrogen peroxide was efficiently decomposed on Pt-Pd surface deposited on Nafion membrane. Comparing the activities for the different materials, the activity for the decomposition of hydrogen peroxide was found to decrease in the order of Pt-Pd surface N MnO 2 N K 2 Cr 2 O 7 N Au N Polycrystalline Pt plate. Kinetics and thermodynamics of the decomposition process were investigated. It was observed that the decomposition process followed bimolecular first order kinetics, which was well fitted with Eley-Rideal (E-R) model. In this paper, the reason of efficient catalytic decomposition of hydrogen peroxide over bi-metallic Pt-Pd surface has been discussed.
