Abstract

The kinetics of heterogeneous decomposition of hydrogen peroxide on fine particle ferrites, $MFe_20_4$, and cobaltites, $MCo_2O_4$, where M = Mn, Fe, Co, Ni, Zn and Mg, have been investigated. The decomposition of $H_2O_2$, was found to be first order at low concentration (0.3%) and zero order at high concentration (30%) of $H_20_2$. The catalytic activity of cobaltites on the decomposition of $H_20_2$ is found to be better than ferrites. The observed catalytic behaviour of ferrites and cobaltites has been attributed to their fine particle nature, large surface area and electronic structure.
