摘要：Metal sulfide-based homojunction photocatalysts have been extensively explored with improved photocatalytic performance. However, the construction of metal sulfide-based S-scheme homojunction remains a challenge. Herein, we reported the fabrication of two-dimensional (2D) CdIn₂S₄ nanosheets coated with three-dimensional (3D) CdIn₂S₄ octahedra (referred to as 2D/3D n-CIS/o-CIS) S-scheme homojunction photocatalyst by simply adjustment of polyvinyl pyrrolidone amount during the solvothermal synthesis. The formation of S-scheme homojunction within n-CIS/o-CIS has been systematically investigated via a series of characterizations, which can generate an internal electric field (IEF) to facilitate the separation and migration of photogenerated electron-hole pairs. The 2D/3D n-CIS/o-CIS composite exhibits significantly improved photocatalytic activity and stability in the selective oxidation of phenylcarbinol (PhCH₂OH) to benzaldehyde (PhCHO) when compared to pure n-CIS and o-CIS samples under visible light irradiation. It is hoped that this work could contribute novel insights into the development of metal sulfides S-scheme homojunction photocatalysts for solar energy conversion.
