The microsphere Bi2WO6has been synthesized by a facile hydrothermal method by using Bi (NO3)35H2O, H40N10O41W125H2O and CO(NH2)2(urea) as the starting materials. The as-synthesized Bi2WO6was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM),BET and UV-vis absorption spectroscopy. The visible-light-responsive photocatalytic activity of Bi2WO6microspheres was evaluated by the photo-degradation of RhB under Xe lamp irradiation. The degradation is up to 96% in 3h. The results show that microsphere Bi2WO6exhibited excellent photocatalytic activity. The reasons for the high photocatalytic activity have been discussed carefully.

CuInS2/Mg(OH)2 (CIS/Mg(OH)2) nanosheets have been prepared for the visible light activated photodegradation of tetracycline hydrochloride (TCH). The introduction of CuInS2 has proven to enhance the photocatalytic activity of Mg(OH)2 nanosheets. It’s ascribed to the enhanced transfer and separation of charge carriers at the junction interface between CuInS2 and Mg(OH)2. The photocatalytic activity of obtained CIS/Mg(OH)2 is greatly affected by CuInS2 content, pH value, and inorganic ions. Among these samples, 2-CIS/Mg(OH)2 exhibits the excellent photocatalytic activity and durability for the visible light driven removal of TCH after five cycle times. Atomic force microscope (AFM) images indicate that the surface roughness of 2-CIS/Mg(OH)2 is intensively influenced in adsorption-photocatalysis process. The •O2− and •OH radicals are vital for the visible light driven photocatalytic activity of 2-CIS/Mg(OH)2 for TCH removal.

Degradation Of Methyl Orange

Bi2WO6-WO3heterojunctions were first prepared using hydrothermal method with the assistance of cetyltrimethylammonium bromide (CTAB). And Bi2WO6-WO3was further fabricated by depositing Pt on the surface using the photo-assisted deposition method. These catalysts were characterized by XRD, SEM, FTIR, BET and DRS. It is found that Pt-Bi2WO6-WO3acting as a novel visible light-driven photocatalyst exhibited excellent photocatalytic activity in degradation of Methyl Orange (MO) under visible light irradiation. The highest photocatalytic activity of Pt-Bi2WO6-WO3photocatalyst is attributed to the synergistic effect of Pt surface plasmon resonance and Bi2WO6-WO3heterojunction structure.

Degradation Of Pollutants

Photocatalytic technology as a means of degradation of pollutants had been widespread concerned. In the past three decades, titanium dioxide (TiO2) has become one of the most extensively studied metal oxides because of its excellent photocatalytic activity and photoinduced hydrophilicity[1,. But TiO2only absorbs wavelengths in the near-UV region (λ<400nm), which is about 3% of the solar spectrum and 53% visible light was can not efficiently utilized for the degradation of organic pollutants. Therefore, it is crucial to explore visible-light-induced photocatalysts. In recent years, in addition to traditional oxides, some complex oxides have been found under visible light driven have a good photocatalytic activity, Such as, N-doped TiO2[, BiOX (X=Cl, Br, I)[, Bi2MoO6[and so on. Nevertheless, such efforts have not achieved satisfactory results aspects of making full use of the visible-light. Therefore, it is still a great challenge to design efficient visible-light driven photocatalysts.
