Abstract
WO3 nanorods and flower-like CuS were synthesized by a hydrothermal process. The visible light driven CuS-WO3 photocatalyst was prepared by adding different weight ratios (10-40%) of CuS on WO3 by a wet impregnation method. The synthesized photocatalysts were characterized by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Field emission scanning electron microscopy (FE-SEM), High-resolution transmission electron microscopy (HR-TEM), energy dispersive X-ray spectroscopy (EDAX) and UV-vis diffuse reflectance (DRS) spectroscopy. The photocatalytic performance of synthesized photocatalysts was evaluated for the photodegradation of methylene blue (MB) under visib..
