Summary: In this study, a novel ternary g-C3N4/Zn2SnO4/MoS2 nanocomposite was prepared by hydrothermal method and exhibited efficient photocatalytic activity towards tetracycline (TC). The structural, morphological, electronic and optical characteristics of the prepared catalysts were examined using various techniques. The obtained ternary composite showed efficient photodegradation of TC, with a degradation rate 2.5 times higher than the pristine samples. Moreover, the optimum catalyst demonstrated good recycle stability and hydroxyl radicals and superoxide radicals were found to be the key active species in TC degradation. This study offers a new perspective on developing highly effective and recyclable photocatalysts for removing aqueous pollutants.

Summary: The mixture of triphenylamine (TPA) and phenyl phenothiazine (PTH) fragments in extended polyimine structures showed varying photocatalytic activities in the degradation of different pollutants under visible light irradiation. Materials with PTH as the sole photoactive unit exhibited the most active photocatalytic performance for polybrominated diphenyl ether-1 and Sudan Red III degradation, while the covalent organic framework containing only TPA was the best photocatalyst for degrading Methylene Blue. These differences were attributed to the versatile abilities of PTH to trigger both photoredox and energy transfer processes, compared to TPA which primarily acts as an energy transfer catalyst.

Summary: Harmful algal blooms pose a threat to aquatic ecosystems and human health. Visible light-driven photocatalysis has gained attention for algae inactivation due to its low cost, stability, and high removal efficiency. However, the limited utilization of visible light and the rapid electron-hole recombination are challenges for traditional photocatalysts. This review summarizes the recent modifications made to enhance the anti-algae performance of visible light-driven photocatalysts. It also discusses the mechanisms of reactive oxygen species-induced damage to algal cells and photocatalytic degradation of organic matter. Additionally, factors such as photocatalyst dosage, algal concentration and species, and water matrix properties that affect the efficacy of visible light-driven catalytic oxidation for algae removal are outlined. The review concludes with perspectives on the emerging field of visible light-driven photocatalytic inactivation.
