Efficient hydrogen peroxide decomposition on bimetallic Pt-Pd surfaces

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>MnO2>K2Cr2O7>Au>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 IN-metallic Pt-Pd surface has been discussed (C) 2010 Elsevier BV All rights reserved
