Abstrakt:	Oxidation is very slow on supported metals or oxides whose contact surface between the catalytic active phase and the carbonaceous particle to burn is poor. On the contrary, some pure oxides are more active. Oxidation by oxygen proceeds by partial reduction of the oxide and the rate-determining step of the reaction is the reoxidation of the reduced solid. Addition of a small amount of platinum catalyzes that reoxidation.
