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.

A novel kind of cyanuric-acid-modified graphitic carbon nitride (g-C3N4)/kaolinite (m-CN/KA) composite with enhanced visible light-driven photocatalytic performance was fabricated through a facile two-step process. Rhodamine B (RhB) was taken as the target pollutant to study the photocatalytic performance of the synthesized catalysts. It is indicated that the cyanuric acid modification significantly enhanced photocatalytic activity under visible light illumination in comparison with the other reference samples. The apparent rate constant of m-CN/KA is almost 1.9 times and 4.0 times those of g-C3N4/kaolinite and bare g-C3N4, respectively. The superior photocatalytic performance of m-CN/KA could be ascribed, not only to the generation of abundant pore structure and reactive sites, but also to the efficient separation of the photogenerated electron-hole pairs. Furthermore, the possible photocatalytic degradation mechanism of m-CN/KA was also presented in this paper. It could be anticipated that this novel and efficient, metal-free, mineral-based photocatalytic composite has great application prospects in organic pollutant degradation.
