The comparative study of Fe-, Mn- and Cu-oxide catalysts supported on α-Al2O3, TiO2, CeO2 and pure graphite-like porous carbon Subunit in the catalytic wet peroxide oxidation by hydrogen peroxide in a stirred batch reactor at 90 °C was performed. The Fe-containing samples supported on α-Al2O3 are sufficiently active and most stable and selective in respect to the CO2 evolution. Cu-containing catalysts are most active, Fe-containing catalysts appear to be much more stable and ecologically benign. The pure Subunit has shown an appreciable activity and highest selectivity in respect to CO2. Hydroquinone and pyrocatechol have been found in the liquid phase as intermediates of the oxidation. Kinetics of the change of the phenol, hydrogen peroxide as well as intermediates concentration has been recorded. The oxidation of phenol over Subunit is assumed to occur via a mechanism, which is different from that for the oxide catalysts.
