Mn‐Dependent Morphology and Structure of SnS2 Nanosheets and the Photocatalytic Performance

“…Sulfur vacancies in Cu‐doped SnS 2 photocatalyst improved the separation efficiency of photogenerated carriers and increased the carrier density [19] . However, electron‐hole easy recombination and charge transfer still have obvious impact on photocatalytic efficiency of SnS 2 material [20] . Self‐assembled morphology and structures with wrinkles and folds may endow 2D materials distinct electronic and photoelectrical properties, [21,22] and heteroatom introduction can also change the charge distribution, energy gap and photocatalytic activity [23] .…”

“…[19] However, electron-hole easy recombination and charge transfer still have obvious impact on photocatalytic efficiency of SnS 2 material. [20] Self-assembled morphology and structures with wrinkles and folds may endow 2D materials distinct electronic and photoelectrical properties, [21,22] and heteroatom introduction can also change the charge distribution, energy gap and photocatalytic activity. [23] Therefore, the stacking structures from layers provide function and great potential for improvement of dichalcogenides' performance.…”

Recent Advances in Aerobic Photo-Oxidation over Small-Sized IB Metal Nanoparticles

“…Qin et al reported a method to dope a mono-Ag-atom at the central site of Au13Ag12(PPh3)10Cl8 nanoclusters with a rod-shape and finally prepared a new kind of "pigeon-pair" cluster, which is called [40,41]. The single-atom exchange between nanoclusters with the same structure resulted in an obvious disturbance to the electronic characters, which could lead to a difference in catalytic performance [42][43][44]. In order to investigate the influence of a single-atom exchange in the catalytic reaction, Au13Ag12 and Au13Ag12•Au12Ag13 clusters were both supported on TiO2 and used in the photocatalytic conversion of ethanol [45]; the reaction proceeded under a UV irradiation at 30 °C.…”

“…Qin et al reported a method to dope a mono-Ag-atom at the central site of Au 13 Ag 12 (PPh 3 ) 10 Cl 8 nanoclusters with a rod-shape and finally prepared a new kind of "pigeon-pair" cluster, which is called {[Au 13 Ag 12 (PPh 3 ) 10 Cl 8 ]•[Au 12 Ag 13 (PPh 3 ) 10 Cl 8 ]} 2+ [40,41]. The single-atom exchange between nanoclusters with the same structure resulted in an obvious disturbance to the electronic characters, which could lead to a difference in catalytic performance [42][43][44]. In order to investigate the influence of a single-atom exchange in the catalytic reaction, Au 13 Ag 12 and Au 13 Ag 12• Au 12 Ag 13 clusters were both supported on TiO 2 and used in the photocatalytic conversion of ethanol [45]; the reaction proceeded under a UV irradiation at 30 • C. As can be seen from Figure 4, Au 13 Ag 12 •Au 12 Ag 13 clusters achieved a higher conversion of ethanol, which is about 1.5-fold compared with the Au 13 Ag 12 clusters (23%), and the selectivity of ethanal for the Au 13 Ag 12 •Au 12 Ag 13 clusters (79%) is slightly higher than the Au 13 Ag 12 clusters (72%).…”

Construction of a Bi2MoO6/CoOx/Au system with a dual-channel charge transfer path for enhanced tetracycline degradation

“…Additionally, Au could improve visible-light absorption and promote the utilization of solar energy owing to the localized surface plasmon resonance (LSPR) effect. [31][32][33][34] Besides, 2D BMO possesses a large specific surface area, which contributes to directing the surface charge transfer instantly and targeting the photoexcited electrons to Au effectively, thus constructing an efficient electron transfer channel. 35,36 Nevertheless, Au is mainly dedicated to providing a single transport channel for photoexcited electrons.…”
