Novel non-porous Ag3PO4/AlPO4 composites with a stick shape were synthesized using the homogeneous precipitation method and characterized by XRD, FESEM, XPS, UV-vis spectroscopy and BET method. The photocatalytic performance was evaluated by degradation of MB and MO upon irradiation with visible light. Results indicate that when the molar ratios of Ag3PO4 to AlPO4 are 6:4 or higher, remarkable increases in photocatalytic activity were observed compared with the pure Ag3PO4 powder. The possible mechanism of photocatalytic degradation of dyes by Ag3PO4/AlPO4 composites was proposed.

A new protocol was developed to obtain a composite photocatalyst by incorporating indium to ZnO and subsequently assembling it with reduced graphene oxide (RGO) sheets. The incorporation of indium led to lattice distortion of ZnO and introduction of defect levels. The hybridization with RGO could improve the electron transport and extend the lifetime of photo-generated carriers, leading to enhanced activity for dye degradation driven by visible light. The photocatalytic activity appeared to be dependent on the relative quantity of RGO. The optimized quantity resulted in the highest activity due to the dual role of electron shuttle and "shielding effect" of RGO. In addition, the composite photocatalyst exhibited excellent repeatable use performance, suggestive of its high stability. This study proposed a promising strategy to construct photocatalysts by rational bandgap engineering and tunable composite technology.

Novel Blue Fescue-like CQDs/Sn-doped ZnO composite photocatalyst was successfully synthesized via a gentle hydrothermal method. The hierarchical CQD/Sn-doped ZnO samples are assembled by many hexagonal prism-shaped nanoneedles. In addition, the photocatalytic performance of all samples was obtained by degrading rhodamine B(RhB) under visible light irradiation. The degradation results indicate that the photocatalytic activity of CQDs/Sn-doped ZnO is better than Sn-doped ZnO, CQDs/ZnO, pure CQDs and pure ZnO. The stability and reusability of CQDs/Sn-doped ZnO were confirmed by cyclic degradation experiments. It can be considered that the effective photocatalytic performance is attributed to the adsorption and transfer of electrons by CQDs.
