An electrostatic adsorption approach was used to realize a composite structure in which larger WO3crystalline particles were surrounded by TiO2nanoparticles. The Pt/WO3–TiO2composite photocatalyst showed a high activity under visible light irradiation (λ> 420 nm).

Chemical Coprecipitation Method

We report on the synthesis and photocatalytic activity of 10 wt% In2O3/BiOCl composite photocatalyst. The 10 wt% In2O3/BiOCl composite photocatalyst was synthesized by a simple chemical coprecipitation method at room temperature followed by thermal treatment at 400 °C for 2 h. During thermal treatment at 400 °C for 2 h, the amorphous-to-crystalline phase transformation occurs in In2O3. Pure BiOCl possesses flower-like nanostructures composed of nanoplates with single-crystal nature. With the incorporation of 10 wt% In2O3, the morphology of the composite photocatalyst is mainly constituted of particles with two different forms: nanoflowers of BiOCl and nanoparticles of In2O3. The effect of 10 wt% In2O3 on the photocatalytic activity of the composite photocatalyst was evaluated for the degradation of Rhodamine B (RhB) under visible light irradiation. The 10 wt% In2O3/BiOCl composite photocatalyst shows enhanced photocatalytic activity compared to pure BiOCl. Based on the results obtained in this study, the mechanism for the enhanced photocatalytic activity of 10 wt% In2O3/BiOCl composite photocatalyst is discussed.

Synergic Effect

CdS/Ag2S/g-C3N4 ternary composites showed excellent photocatalytic performance toward H2 evolution. Their improved photocatalytic activity could be attributed not only to the synergic effect, but also to the introduction of Ag2S.
