Synergistic effects of the Rh–S bond and spatially separated dual cocatalysts on photocatalytic overall water splitting activity of ZnIn₂S₄ nanosheets under visible light irradiation

Abstract

Photodeposition of dual-cocatalysts Pt-Cr or Rh-Cr on the surface of ZnIn2S4 is used to achieve overall water splitting. Compared with the hybrid loading of Pt element and Cr element, the...

Integrating Co(OH)2 nanosheet arrays on graphene for efficient noble-metal-free EY-sensitized photocatalytic H2 evolution

“…1–5 Hydrogen is an efficient and green energy source carrier. 6–8 Solar photocatalytic water splitting into hydrogen is one of the most prospecting energy transformation technologies. 9–13 In the photocatalytic H 2 evolution system, cocatalysts can promote the migration of photogenerated charge carriers and offer catalytic active sites for H 2 evolution.…”

Recent progress in polymer nanosheets for photocatalysis

“…In addition, solardriven degradation of pollutants (such as volatile organic compounds, antibiotics and organic dyes) is a powerful technology to solve the problem of environmental pollution. [26][27][28][29][30][31] Since the successful application of TiO 2 in photocatalytic water splitting, 32 a large number of inorganic photocatalysts have been explored, such as oxides (NaTaO 3 , ZnO, and SrTiO 3 ), [33][34][35] suldes (In 2 S 3 and ZnIn 2 S 4 ) [36][37][38] and oxynitrides (Ta 3 N 5 , LaTiO 2 N, and BaTaO 2 N). [39][40][41] Although a series of advances have been achieved in photocatalysis, they usually exhibit low quantum efficiency due to rapid carrier recombination.…”

Research Progress of ZnIn2S4-Based Catalysts for Photocatalytic Overall Water Splitting

“…The photocatalytic activity can be influenced by adjusting the amount of co-catalyst loading, the type of co-catalyst, the shape of the co-catalyst, etc. In 2023, Jing et al prepared spatially separated double-coordinated co-catalyst ZnIn 2 S 4 composites [109]. They first prepared the hexagonal crystalline phase ZnIn 2 S 4 by the hydrothermal method, and then prepared ZnIn 2 S 4 -Pt-Cr and ZnIn 2 S 4 -Rh-Cr by photo-deposition with Pt-Cr and Rh-Cr co-catalysts loaded on the surface of ZnIn 2 S 4 .…”
