AgBr/Polyoxometalate/Graphene Oxide Ternary Composites for Visible Light-Driven Photocatalytic Hydrogen Production

“…The increasingly serious energy crisis and the environmental issues caused by the exhaustion of traditional fossil fuels have resulted in an aggressive search for renewable and environmentally friendly alternative energy. − Hydrogen energy as a clean and renewable energy source has been considered as a promising alternative to replace traditional fossil fuels. − Photocatalytic H 2 evolution from water by solar irradiation has received considerable attention because of its potential application in a future hydrogen economy, in which the development of high-efficient photocatalysts is the pivotal issue. − Very recently, various of novel semiconductor photocatalysts such as metal oxides, sulfides, oxynitrides, heterostructures, and polymers have been investigated as photocatalysts for water splitting or pollutant degradation under visible light irradiation. − Among them, Ag-based nano-photocatalysts have attracted increasing attention because of their considerably good photocatalytic response, such as g-C 3 N 4 -Ag/AgBr, Ag/AgBr/g-C 3 N 4 , Ag/SnNb 2 O 6 , and so on. − However, most of these Ag-based photocatalysts have a relatively low capability to separate photogenerated charge carriers and suffer from the slow deactivation. Therefore, developing a strategy that can improve the performance of Ag-based photocatalysts is highly desired.…”

Selective CO2-to-CO photoreduction over an orthophosphate semiconductor via the direct Z-scheme heterojunction of Ag3PO4 quantum dots decorated on SnS2 nanosheets

“…Moreover, this image reveals an additional ultra-thin carbon layer on the SnS 2 surface due to the residue of the l -cysteine precursor. 41,56 After heterostructuring, Ag 3 PO 4 quantum dots, with an average characteristic size of ∼10.0 nm, are uniformly decorated on the SnS 2 surface (Fig. 2a and b).…”

Enhancing mechanism of electron-deficient p states on photocatalytic activity of g-C3N4 for CO2 reduction

“…One critical factor affecting catalytic activity is the high electron-hole recombination rate associated with the electronic properties of catalysts. 31 Several studies have carried out structural modications to address this, such as metal-doping, [32][33][34][35] which leads to the lower recombination of photogenerated carriers, and nonmetal doping (e.g. S, O, and N), which exhibits a remarkable enhancing effect on catalytic properties because of geometrical and electronic effects.…”
