In recent decades, a great interest in photocatalytic water splitting has been due to the importance of sunlight hydrogen production as renewable energy source reduce global warming effects. The applications metal sulfide semiconductors photocatalysts, chalcogenide compounds, with advantages wide range for light harvesting and tunable bandgap, may be restricted by limited active sites, poor conductivity, photo corrosion, charge recombination. sulfur vacancy (SV) effectively addresses these issues generates H2 O2 attaining adequate water-splitting because improved optoelectronic features. This review article aims comprehensively highlight synergistic roles SV sulfides amended overall activity. SV-modulated sulfides' features are deliberated, followed different advanced synthetic techniques effectual defect generation. specific aspects refining optical range, dynamics carrier, photoinduced surface chemical reactions deeply described applications. Finally, summarized vouchsafing outlooks opportunities confronting S-vacancy engineered sulfides-based photocatalysts elucidated. It would expected hoped that this will help researchers design/fabricate better sulfide-based systems.

Journal of Materials Science, Год журнала: 2025, Номер unknown

Опубликована: Янв. 15, 2025

Abstract As the demand for sustainable energy solutions grows, developing efficient conversion and storage technologies, such as fuel cells metal-air batteries, is vital. Oxygen Reduction Reaction (ORR) a significant limitation in electrochemical systems due to its slower kinetics. Although Pt-based catalysts are commonly used address this challenge, their high cost suboptimal performance remain obstacles further development. This review offers comprehensive overview of advanced support materials aimed at improving efficiency, durability, cost-effectiveness catalysts. By examining range materials, including mesoporous carbon, graphene, carbon nanotubes, metal oxides, clarifies relationship between structural properties these supports influence on ORR performance. Additionally, it discusses fundamental characteristics practical applications cells, explores potential future directions optimizing advance technologies. Future research could focus nano-engineering composite material development unlock full catalysts, significantly enhancing economic viability applications.
