| Summary: | 碩士 === 國立彰化師範大學 === 化學系 === 106 === In this study, different ways to prepare reduced graphene oxide (rGO) doped with solvothermal synthesized BiOCl for the formation of BiOCl/rGO heterostructures were proposed. The heterostructures with different compose of graphene oxide (GO) and reduced graphene oxide (rGO) were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and X-ray diffraction (XRD). The prepared heterostructures provided a band gap of 3.12 eV through UV-Vis Diffuse Reflectance Spectroscopy (UV-Vis DRS). Comparing to pure BiOCl, the prepared BiOCl/rGO exhibited higher photocatalytic activity toward Rhodamine B (93.3% degradation efficiency within 20 min-visible light irradiation). The prepared BiOCl/rGO heterostructures possessed advanced properties including easy preparation, and higher photocatalytic activity under visible light irradiation. It possesses a good performance for the photocatalytic degradation of organic pollutants and bacteria in environmental water samples in the future.
