Dy-doped BiOCl powder photocatalyst was synthesized A one–step coprecipitation method. The incorporation of Dy3+ replaced partial Bi3+ in BiOCl crystal lattice system. For Rhodamine B (RhB) under visible light irradiation, 2% Dy doped BiOCl possessed highly efficient photocatalytic activity and photodegradation efficiency. The photodegradation ratio of RhB could reach 97.3% after only 30 min of photocatalytic reaction; this was more than relative investigations have reported in the last two years. The main reason was that the 4f electron shell of Dy in the BiOCl crystal lattice system can generate a special electronic shell structure that facilitated the transfer of electron from valance band to conduction band and separation of the photoinduced charge carrier. Apart from material preparation, this research is expected to provide important references for RhB photodegradation in practical applications.

Eu/BiVO4 photocatalyst was synthesized by a facile one-step hydrothermal method. The structures and morphologies of Eu/BiVO4 photocatalysts were investigated by XRD, SEM and FT-IR and their photocatalytic activity was evaluated by the degradation of tetracycline hydrochloride (TCH) under the visible light irradiation. From the photocatalytic activity test, 1% Eu/BiVO4 displayed more superior photodegradation efficiency with 91.4% degradation efficiency of TCH in 150 min by contrast with 77.3% degradation rate of pure BiVO4. The mechanism has been explored that h+ is the primary active species, and ·OH is a secondary active substance in the photocatalytic process.

Abstract A novel binary BiSI/Ag2CO3 photocatalyst with excellent visible light-driven photocatalytic performance was prepared. The products were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS) and electrochemical impedance spectroscopy (EIS). The photocatalytic activity of the samples were evaluated by photocatalytic degradation of rhodamine B(RhB) under the irradiation of visible light. The results showed that the BiSI improves the photocatalytic activity of BiSI/Ag2CO3. Moreover, when the mass ratio of BiSI in BiSI/Ag2CO3 composites was 40%, the as-prepared BiSI/Ag2CO3 composite exhibited the best photocatalytic activity for degrading RhB. Finally, the possible mechanism for photodegradation over the BiSI/Ag2CO3 composites is also proposed.

The MoS2/ZnS binary heterojunctions obtained by a facile one-step hydrothermal route is competent to retrench the forbidden energy gap by creating sulfur vacancies. The tailoring of the lattice parameters of sulfides for interfacial charge transfer through the heterojunctions enhanced photocatalytic activity.
