Summary: This study introduces a novel composite material composed of carbon nitride and anatase nanocrystals. The addition of ultrafine carbon nitride induces the generation of oxygen vacancies and the growth of anatase (001) facets. The composite exhibits exceptional photocatalytic performance, with a degradation rate of 2,4-dichlorophenol almost 3.8 times higher than pure TiO2 nanofibers. Furthermore, the composite shows excellent degradation efficiency and stability even under low temperature and long-term photocatalytic process.

Summary: The Cu/TiO2/FA composite was optimized for the removal of the model dye pollutant methyl orange under visible light irradiation using response surface methodology and Box-Behnken experimental design. The study considered three independent variables and achieved a 99.91% removal rate under the optimal operating conditions. The results support the hypothesis of a combined and synergic adsorption-photocatalytic degradation process for pollutant removal.

Summary: AgIO3 is a wide bandgap photocatalyst that can only be activated by UV irradiation. Under visible light irradiation, AgIO3 exhibits photocatalytic activity through a dye sensitization mechanism, degrading dyes RO and EY. During the degradation process of RO or EY, metallic Ag is generated on the surface of AgIO3, and this Ag/AgIO3 product can degrade other dyes such as MB and CV under visible light irradiation.
