Abstract
A series of ZnO/ZnWO4 nanocomposites with different ZnWO4 content based on ZnO and WO3 nanopowders electrochemically synthesized under pulse alternating current was obtained. A complex of physicochemical methods (X-ray diffraction, Raman spectroscopy, transmission electron microscopy, energy dispersive X-ray microanalysis) was used to study the composition and structural characteristics of the obtained materials. The nanocomposite with optimal composition (ZnO 90%, ZnWO4 ~6%) was used as a photoanode material for a flow photocatalytic fuel cell with sulfate electrolyte with the addition of organic and inorganic fuel. The maximum values of Eoc and Pmax, which were 850 mV and 85.8 μW/cm2, respectively, were achieved using Na2SO4 with the addition of glucose as a fuel.
