Photo-catalysts on the basis of quasi-unidimensional state of cobalt and copper activated

Abstract

Zn1-xMxO (0 ≤ x ≤ 0,1) solid solutions with tubular morphology of aggregates and Zn1-xMxO1-yCy : nMO (0,1 ≤ x ≤ 0,3) composites were obtained using formate-glycolate complexes Zn1-xMx(HCOO)(OCH2CH2O)1/2 (M = Co, Cu; 0 ≤ x ≤ 0,3). The materials are tested in the oxidation of 1,4-dihydroxybenzene under the action of visible radiation. It is established that copper in Zn1-xMxO (0 ≤ x ≤ 0,1) is more effective than cobalt. Its presence in composites leads to a decrease of the photocatalytic activity.
