Oxygen-doping of ZnIn2S4 nanosheets towards boosted photocatalytic CO2 reduction

ZnIn2S4‐Based Photocatalysts for Energy and Environmental Applications

“…Due to the above characteristics, the Odoped ZnIn 2 S 4 ultrathin nanosheets exhibited an extraor dinarily enhanced photocatalytic performance with a H 2 produc tion rate of about 2120 µmol h −1 g −1 , almost 5.5fold than that of the pristine ZnIn 2 S 4 nanosheets. In 2020, Odoped ZnIn 2 S 4 ultrathin nanosheets were also reported by Wang et al, [94] which confirmed the important roles that O doping played in the modi fication of the intrinsic properties and photocatalytic CO 2 reduc tion perfomance of ZnIn 2 S 4 photocatalysts.…”

“…However, for the unmodified ZnIn 2 S 4 material, neither hexagonal phase nor cubic phase are highly active for CO 2 photoreduction, owing to the high recombination rate of photogenerated electron-hole pairs. In view of this, various of modification strategies for ZnIn 2 S 4 photocatalyst have been applied to enhance its performance for CO 2 reduction, including morphology engineering by fab rication oneunitcell ZnIn 2 S 4 layers, [30] doping engineering by introducing oxygen heteroatom, [94] vacancy engineering by preparing Zn vacanciesrich ZnIn2S 4 , [30,70] and heterojunction engineering by constructing a variety of ZnIn 2 S 4 based het erojunctions. [31,70,143,165,182,221,303,330,401,402] As an typical example, to pursue the high activity of CO 2 reduction and simultane ously elucidate the promotion mechanism, in 2017, Xie et al [30] rationally designed and fabricated the Zn vacanciesrich and atomiclayerthick ZnIn 2 S 4 nanosheets.…”

Construction of a hierarchical ZnIn2S4/C3N4 heterojunction for the enhanced photocatalytic degradation of tetracycline

“…65-2023). [35][36][37] The characteristic peaks of TCN were found at around 13.1°and 27.4°, which are associated with the (100) in-planar repeated units and (002) stacking layered structure, respectively. 38 The ZIS/TCN-3 composite displayed the characteristic signals of ZIS and TCN, Scheme 1 Schematic illustration of the synthesis process of ZIS/TCN heterojunctions.…”

Sustainable ferrate oxidation: Reaction chemistry, mechanisms and removal of pollutants in wastewater

“…It is possible to describe the primary treatment of AOPs in two steps: one is the generation of hydroxyl radicals (OH • ), and the other is the oxidative reaction of pollutants with the generated radicals. The generation of (OH (Pan et al, 2020b;Yonar, 2011). Advanced oxidation techniques can easily and generally remove hormones, pharmaceuticals, and dyes (Mackul'ak et al, 2013;Yang et al, 2017).…”
