The kinetics of H2O2 decomposition was studied at 1.5-42° and pH 2-10 and the stabilities of the MnO, MnO2, Mn2O3, and Mn3O4 catalysts was detected after treating them repeatedly with the same concentration of H2O2 solutions. The catalytic activity of the oxides changed symbatically with their electrode potential. Only in the presence of MnO2 was the reaction of the 1st-order; in the presence of the remaining oxides, it was of order <1. The lowest activation energy (6.4-8.5 kcal/mole) was observed for MnO2 catalysis. The nonsteady-state nature of the decomposition and a correlation between the catalytic activity and active O concentration on catalyst surfaces are discussed.
