“…To date, various visible-light-active photocatalysts, such as CdS [11], Bi2WO6 [12], g-C3N4, etc. [13][14][15][16][17], have been constructed and used in redox reactions.…”

A CdS/MnS p–n heterojunction with a directional carrier diffusion path for efficient photocatalytic H2 production

“…[12][13][14] As we all know, the activity of a photocatalyst is determined by the utilization rate of sunlight, the separation efficiency, the surface diffusion rate of the photogenerated carriers and the redox reaction rate of photogenerated electron-hole pairs participating in the reaction. [15][16][17][18] The separation efficiency of photogenerated carriers can be improved by constructing heterojunctions. Sheng et al reported a ZnO/TiO 2 Z-scheme photocatalyst, and the photocatalytic activity of hydrogen production and oxidation performance were significantly improved compared with the single phase.…”

Challenges and prospects in the selective photoreduction of CO2 to C1 and C2 products with nanostructured materials: a review

“…H 2 O is employed as both a reductant (an electron donor) and hydrogen source for CO 2 reduction to various C1 and C2 products in the liquid phase photocatalytic process. CO 2 reduction and H 2 generation from the splitting of water 188–190 during the photoreduction of the CO 2 process can occur concurrently and competitively. After the formation of photogenerated charge carriers, the holes are trapped and utilized by H 2 O, resulting in H 2 O splitting and the generation of O 2 & H + , respectively.…”
