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.

As one of the best sustainable approaches for visible-light production hydrogen (H2) to meet energy demands, semiconductor-based photocatalysis has received broad interest in recent decades. The fundamental restrictions graphitic carbon nitride (g-C3N4) as a promising metal-free photocatalytic semiconductor water splitting, like insufficient harvesting and high electron–hole (e/h) pairs recombination, have limited its applications this goal. In regard, optical, charge separation, surface features g-C3N4 can be tuned via engineering C/N vacancies, which is reviewed here splitting by g-C3N4. Reports confirm that enhanced resulting from vacancies are helpful adsorption on surface, improving water-splitting kinetics. First Review, improvements structural optical characteristics introducing especially nitrogen will discussed illustrate better performance. Then, various strategies creating controlling reviewed. critical roles optimizing performance also described, finally advances defective oxidation addressed.
