Abstract
Under ultraviolet (UV) and visible light irradiation, semiconductive photocatalysis is leading to the disinfection and mineralization of organic compounds and other harmful contaminants. Some heavy metals and refractive organic compounds are not transferred to the next step, making mineralization difficult. The current study uses a straightforward hydrothermal technique to synthesise BiVO4/Au/Black phosphorene, a semiconductive composite photocatalyst. Black phosphorene levels in the composite ranged from 1 to 3%. Overall, four samples were created, with the composite with a 3% black phosphorene content being the most effective in the photodegradation of methylene blue. Ultraviolet (UV-vis) and photoluminescence (PL) spectroscopies were employed to assess the optical characteristics of the materials, whereas X-ray diffraction (XRD) and scanning electron microscope (SEM) were utilised to determine the morphology and crystallinity. The bandgap of the produced photocatalysts ranged from 2.5 to 2.25 eV, with decreased recombination when the quantity of black phosphorene in the composite was increased.
