Summary: In this study, a ternary photocatalyst of g-C3N4/Ag-TMCs was prepared by photodepositing Ag nanoparticles on the surface of titanium dioxide mesocrystals followed by loading them on g-C3N4. The prepared photocatalyst exhibited excellent photocatalytic activity and the deposited Ag content positively influenced the photocatalytic degradation efficiency. The improved photocatalytic properties were attributed to the synergistic effect created by the LSPR effect of Ag, electron-conduction bridge role of Ag, and the heterojunction structure formed between Ag, TMCs, and g-C3N4.

Summary: Black TiO2 with abundant oxygen vacancies (OVs)/B-doped graphitic carbon nitride (g-C3N4) Z-scheme heterojunction nanocomposites were prepared by a one-pot strategy. The OVs enhance photogenerated carrier separation and the sorption and activation of antibiotic compounds (tetracycline hydrochloride, TC). The prepared heterojunction photocatalysts with a narrow bandgap of similar to 2.13 eV exhibit excellent photocatalytic activity for the degradation of tetracycline hydrochloride (65%) under visible light irradiation within 30 min, which is several times higher than that of the pristine one. The outstanding photocatalytic property can be attributed to abundant OVs and B element-doping reducing the bandgap and extending the photo-response to the visible light region, the Z-scheme formation of heterojunctions preventing the recombination of photogenerated electrons and holes, and promoting their effective separation.

Summary: In this study, g-C3N4/diatomite composites were synthesized by mixing melamine and diatomite in hydrochloric acid aqueous solution and calcining the mixture at 550 degrees C for 2 hours. The CN/DE-10 composite exhibited the best photocatalytic performance, degrading over 95% of RhB solution in 50 minutes, with a reaction rate constant 6.4 times that of pure g-C3N4. The enhanced specific surface area, improved light absorption ability, and reduced recombination rate of electrons and holes contributed to the outstanding photocatalytic performance of CN/DE-10.
