Abstract
A series of ZnO/ZnWO4 nanocomposites with different ZnWO4 content, are electrochemically synthesized under pulse alternating current starting from ZnO and WO3 nanopowders. A complex of physicochemical methods (X-ray diffraction analysis, 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 (ZnWO4 ~6%) was used as a photoanode material for a flow photocatalytic fuel cell with sulfate electrolyte added with organic and inorganic fuel. The maximum values of Eoc (850 mV) and Pmax (85.8 μW/cm2) are achieved using Na2SO4 with the addition of glucose as a fuel.
