| Summary: | In this work, Bi2WxMo1–xO6 solid solutions and Bi2WO6/g-C3N4 composites were synthesized by a simple hydrothermal method, characterized by a complex of physicochemical methods and used in the decomposition of organic pollutants under visible light to comprehensively compare different modulating techniques. The highest efficiency was detected for Bi2W0.5Mo0.5O6 in the degradation of methylene blue (conversion of 52.9%, TON = 0.022), indicating the attractiveness of the doping strategy. Excellent results were achieved with small amounts of H2O2 in the photodegradation of methylene blue (conversion of 97.9%, TON = 0.040) and phenol (conversion of 81.2%, TON = 0.056). |
