Dual Functions of CO2 Molecular Activation and 4f Levels as Electron Transport Bridge in Dysprosium Single Atom Composite Photocatalysts with Enhanced Visible‐Light Photoactivities

“…Therefore, the use of photocatalysts to achieve an efficient conversion of CO 2 into green energy under the irradiation of clean solar energy is a popular choice of effective means. [ 16–26 ] It is well known that the construction of excellent photocatalytic materials is a necessary means to improve photocatalytic performance. [ 27–31 ] Among the photocatalytic materials reported, the bandgap of graphite carbon nitride (g‐C 3 N 4 ) is ≈2.7 eV, and the conduction band (CB) level is relatively negative, which promotes the reduction capability of photogenerated electrons.…”

In-situ fabrication SnO2/SnS2 heterostructure for boosting the photocatalytic degradation of pollutants

“…The use of co-catalysts, mostly no-ble metals (e.g., Pt, Au, and Pd), has been demonstrated as a successful strategy for improving electron migration. Furthermore, wider absorption semiconductors, such as WO3 [6,16,17], CuO [18,19], CdS [5,20,21], SnS2 [22], MoS2 [23][24][25][26], BiOX (X = Cl, Br, I) [27][28][29][30], BiVO4 [31][32][33][34], g-C3N4 [35][36][37][38][39][40][41][42], and red/black phosphorous [43][44][45], have been employed to greatly enhance photocatalytic efficiency [46]. Up till now, other novel strategies have been investigated to reduce the recombination of photogenerated carriers and accelerate the transfer of electron-hole pairs [40,[46][47][48][49][50][51][52].…”

Inside‐and‐Out Semiconductor Engineering for CO2 Photoreduction: From Recent Advances to New Trends

“…As each of the aforementioned steps needs to be well optimized to achieve highly active and selective photocatalysts, various structural design methods have been developed for promoting the photocatalytic CO 2 reduction performance, as briefly listed in the following: 1) Construction of nano‐/microstructures strategies can control the morphology, size, and shape of materials, which have substantial advantages for enhancing CO 2 photoreduction activity, such as shortening charge migration pathway, [ 126–128 ] increasing reactive catalytic sites, [ 129–133 ] boosting charge separation as well as extending optical transmission length. [ 134–138 ] 2) Doping and formation of solid solution are two main approaches to tailor the crystalline and band structures of photocatalysts. The alteration in atomic composition bonding and coordination may result in the changes of light absorption, [ 139,140 ] band energy edge level, [ 141–143 ] and charge separation.…”
