Summary: CaTiO3 was synthesized using a sol-gel method and decorated with different weight percentages of Ag on the surface using the wetness impregnation method (AgCTO). Characterization of the prepared catalyst showed improved morphology, optical properties, and activity in wastewater remediation. The loading of Ag reduced the band gap and extended the photocatalyst's range to the visible region, mainly due to the localized surface plasmon resonance effect (LSPR). The Schottky junction formed at the CaTiO3 and Ag contact effectively facilitated electron transport, reducing recombination of photoinduced electrons and holes.

Summary: MXene-derived photocatalysts have the potential for developing photo-driven green and sustainable fuel production, but their efficiency is currently low. In this study, a ternary photocatalyst derived from Nb2C MXene was synthesized, leading to improved efficiency and stability in photocatalytic hydrogen production. The optimized ternary photocatalyst composite exhibited the highest H-2 evolution efficiency and maintained high activity after multiple cycles.

Summary: The study found that carbon nanodots can produce dihydrogen gas under light irradiation and have a dual function of light absorption and dihydrogen production without the need for external assistance. Through in-depth physicochemical research, it was discovered that precatalytic activation through reduction with a sacrificial electron donor is crucial for efficient dihydrogen formation.

Summary: In this study, Ag/ZnO photocatalyst was synthesized using a one-pot hydrothermal method in an ethylene glycol medium. The synthesized samples were characterized using various analytical techniques. The results showed that spherical Ag/ZnO exhibited the highest photocatalytic activity due to the formation of the heterojunction interface and the plasmonic resonance effect of silver.
