Abstract: By temolysis of the Zn1− Cu (HCOO)(OCH2CH2O)1/2 complexes in one step Zn1− Cu O solid solutions were obtained. Сopper in these materials is a regulator of the photoactivity and morphology of aggregates. According to TEM, XPS, optical spectroscopy, and voltammetry, all samples studied contain monovalent copper. It was shown that the maximum photoactivity in the reactions of photooxidation of As in UV and blue light has Zn1− Cu O (0<x<0.1) solid solutions with tubular particle morphology. With an increase in concentration up to 10 at.%, сopper manifests itself as an electron acceptor, which reduces the efficiency of the catalyst in both light ranges.
