dc.description.abstract© 2021 Institute of Physics Publishing. All rights reserved.(Photo)electrocatalytic properties of nanostructured WO3 films used for H2 evolution reaction (HER) were modified by forming hybrid structures containing a crystalline 2H-WS2 and an amorphous a-MoSx phases. For this, respectively, thermochemical treatment of metal oxide films in H2S gas and reaction pulsed laser deposition of molybdenum in H2S were applied. The functional characteristics of the hybrid structures were studied in a three-electrode electrochemical cell in an acid solution under intermittent illumination with a Xe lamp. a-MoSx film deposition caused a more significant improvement in the HER activity of MoSx/WO3 structure compared to that of WS2/WO3 structure. However, WS2/WO3 structures were superior to MoSx/WO3 structures in the efficiency of the photoactivated HER. The factors that could influence the (photo)electrocatalytic behaviour of the created structures were analysed.
