g‐C3N4/SnS2 van der Waals Heterostructures Enabling High‐Efficiency Photocatalytic Hydrogen Evolution

“…[5][6][7] In the past decades, numerous semiconductors following the first report by Fujishima [8] on photoelectrochemical H 2 -evolution have been explored to satisfy photocatalytic process, including but not limited to TiO 2 , [9] CdS, [10] Bi 3 O 4 Cl, [11] Bi 2 MoO 6 . [12] In particular, tin disulfide (SnS 2 ) with a shorter average carrier diffusion length, as a typical member of 2D transition metal dichalcogenides (TMDCs), is gradually contribute to superior photocatalytic H 2 evolution activity. [38] Hence, it is desirable to design and synthesize g-C 3 N 4 /SnS 2 vdW heterojunction and investigate its catalytic mechanism in terms of structure-performance correlation.…”

“…[ 5–7 ] In the past decades, numerous semiconductors following the first report by Fujishima [ 8 ] on photoelectrochemical H 2 ‐evolution have been explored to satisfy photocatalytic process, including but not limited to TiO 2 , [ 9 ] CdS, [ 10 ] Bi 3 O 4 Cl, [ 11 ] Bi 2 MoO 6 . [ 12 ] In particular, tin disulfide (SnS 2 ) with a shorter average carrier diffusion length, as a typical member of 2D transition metal dichalcogenides (TMDCs), is gradually demonstrated to be a potential material for future scaled device applications of photocatalysis owing to the advantages of appropriate band position, anisotropic electronic structure, and earth‐abundant. [ 13–18 ] Nevertheless, the practical applications of SnS 2 are seriously hindered by serious recombination of photogenerated carriers and slow hydrogen evolution reaction dynamics.…”

Solvent Effects on Photocatalytic Anaerobic Oxidation of Benzyl Alcohol over Pt-Loaded Defective SrTiO3 Nanoparticles

“…15 Sun et al fabricated surface oxygen vacancy (SOV)-decorated Bi 2 MoO 6−x for selection oxidation of benzyl alcohols (BAs) with benzotrifluoride as the solvent, and the conversion reached 57.8%. 25 In 2019, we employed Rh-doped SrTiO 3 nanoparticles with Pt loading as the photocatalyst for the selective photooxidation of alcohols into corresponding aldehydes or ketones under anaerobic conditions in a water system. In addition, it is worth noting that alcohol oxidation occurs via dehydrogenation even in the presence of water, as confirmed by an isotope-labeled quadrupole mass spectrometer (QMS).…”

“…Chen et al developed Pt x /Zn 3 In 2 S 6 to dehydrogenate benzylic alcohols in 50 mL of benzotrifluoride, and the H 2 output over 2.14% Pt/Zn 3 In 2 S 6 reached up to 950 μmol, which was around 7.5 times higher than that over Zn 3 In 2 S 6 . Sun et al fabricated surface oxygen vacancy (SOV)-decorated Bi 2 MoO 6– x for selection oxidation of benzyl alcohols (BAs) with benzotrifluoride as the solvent, and the conversion reached 57.8% …”

Investigation of the Kinetics and Reaction Mechanism for Photodegradation Tetracycline Antibiotics over Sulfur-Doped Bi2WO6-x/ZnIn2S4 Direct Z-Scheme Heterojunction

“…In 2018, Hao et al found that the induction of surface oxygen vacancies (Sov) in a Z-scheme system possessed several distinct advantages: on the one hand, the introduced Sov facilitated the formation of intimate contact. Simultaneously, it enhanced the separation and migration efficiency of photoexcited carriers due to its built-in electric field; on the other hand, Sov could effectively adjust the band structure to realize the optimized Sov-mediated Z-scheme systems [ 17 ]. Furthermore, Sun et al investigated firstly that Sov-dominated “Electron Bridge” greatly enhanced the spatial separation ability and utilization efficiency of photoexcited carriers [ 18 ].…”
