Abstract

The catalytic photodecomposition of t-butyl hydroperoxide on Al2O3, CaO and MgO and on Vanadium and Molibdenum catalysts supported on above metioned oxides was studied by means of Electronic Paramagnetic Resonance. It was found that during the photodecom­position on Al2O3 and MgO formation of RO2 takes place whilst O2- is formed on CaO. In the case of supported catalysts, a complex with transition metals is formed taking place the reduction of Mo6+ and V5+ to Mo5+ and V4+. Probable reaction mechanisms in both cases are shown and the low probability for RO2 to be a source of active oxigen and to participate in oxidation reactions is suggested, the role of lattice oxigens in the formation of the transition metal-hydroperoxide complex is discussed.
