Catalysis of an oxidation-reduction (redox) reaction in which a diphenol or related substance acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor. Catalysis of the reaction: 2 catechol + O2 = 2 1,2-benzoquinone + 2 H2O. Catalysis of an oxidation-reduction (redox) reaction in which a diphenol, or related compound, acts as a hydrogen or electron donor and reduces oxygen.
