? 2022 Elsevier B.V.Herein, efficient ZnWO4 nanotubes incorporated/BC sheets hybrid photoanodes were designed by controlling the surface charges of the two individual materials via facile hydrothermal method. The prepared hybrid nanocomposites have been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray (EDX), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, photoluminescence (PL) and UV–Visible spectroscopy. XRD and TEM results suggest that monoclinic crystalline structure with 10–15 nm diameter of ZnWO4 nanotubes were uniformly decorated on the outer surface of BC sheet. The BC layer has had a significant impact on the structure and properties of the material, including lattice extension, band-gap reduction, fluorescence enhancement, and photovoltaic activity. The photovoltaic properties of dye-sensitized solar cells were investigated by applying them on the working electrodes. The developed ZnWO4/BC photoanode demonstrated high power conversion efficiency (7.61%), IPCE (78.21%), and long-term stability. The improved mechanism of the proposed photoanode materials are also discussed in detail.
