Article Abstract

The inefficient charge separation and transport remains a bottleneck in photocatalysis. While various strategies have been explored to improve this process, most focus on single-sided modulation either the conduction-band electrons or valence-band holes, limiting overall improvement. Herein, an innovative coupling modification approach is adopted where Ru and α-FeO (FO) nanoparticles are integrated onto ZnInS (ZIS) to prepare Ru/ZnInS/α-FeO, and constructs dual charge transfer pathways for electrons and holes. This bidirectional channel configuration significantly enhances carrier separation and accumulation, enabling Ru as an electron (e) mediator and FO as a hole (h) extraction facilitator, driving simultaneous redox reactions, and enabling substantial improvement in the photocatalytic sulfur oxidation process coupled with hydrogen generation. This approach enhances interface charge separation/spatial accumulation and provides valuable guidance for designing and developing advanced high-efficiency photocatalytic systems.

College of Materials and Chemical Engineering, Key Laboratory of Inorganic Nonmetallic Crystalline and Energy Conversion Materials, China Three Gorges University, Yichang, Hubei 443002, P. R. China.

A novel copper-catalyzed radical cross-coupling reaction for the thioesterification of polyfluoroarenes is developed using KS and aldehydes in water. This protocol employs a readily available KS as a sulfur source, eliminating the need for hazardous thiols and organic solvents. The mild reaction conditions are compatible with a wide range of functional groups, providing access to diverse polyfluoroaryl thioesters.

Iron-based photocatalysis has emerged as a sustainable and versatile platform for facilitating a wide range of chemical transformations, offering an appealing alternative to precious metal photocatalysts. Among the various activation modes, ligand-to-metal charge transfer (LMCT)-driven homolysis of Fe(III)-L(ligand) bonds has garnered considerable attention due to its ability to generate reactive radical species under mild conditions, without requiring the matching of substrates' redox potentials. In this review, we present a comprehensive overview of recent developments in LMCT-driven iron photocatalysis, with a particular focus on both mechanistic insights and synthetic applications published in the last five years.
