ZnIn2S4‐Based Photocatalysts for Energy and Environmental Applications

“…ZnIn 2 S 4 -MoS 2 : Molybdenum disulfide (MoS 2 ), an impor tant type of layered transition metal dichalcogenide (TMD), has attracted interest in the energy and environmental field over the past decades, owing to its unique optical, electronic, and structural features. Various MoS 2 -ZnIn 2 S 4 binary heterojunc tions with wellmatched geometrical structure (2D/2D, [125][126][127] 0D/2D, [33] and 0D/3D [128][129][130][131][132][133][134][135] ) have been reported for energy and environmental applications in recent years. As a notale example, Zhang et al [33] designed and fabricated a 0D/2D mosaic structure MoS 2 /ZnIn 2 S 4 atomiclevel binary het erojunction (Figure 12l).…”

Electrostatic self‐assembly of 2D‐2D CoP/ZnIn2S4 nanosheets for efficient photocatalytic hydrogen evolution

“…[5][6][7][8] Two-dimensional (2D) photocatalysts have been proven to be promising to solve the above-mentioned problems due to their abundant surface-active sites, huge specific surface area, and excellent charge carrier separation. 4,6,[9][10][11][12][13][14] Very recently, ZnIn 2 S 4 (ZIS), especially single/few-layered 2D ZIS has been considered as an outstanding photocatalyst for hydrogen generation, mainly due to its good chemical stability, suitable band gap, and excellent photocatalytic performance. [10][11][12] Nonetheless, as most of semiconductor-based photocatalysts, individual ZIS still reveals unsatisfactory photocatalytic activity due to its rapid electron-hole recombination and large hydrogen evolution overpotential, resulting from lack of driving force for separating photogenerated charge carriers.…”

“…[10][11][12] Nonetheless, as most of semiconductor-based photocatalysts, individual ZIS still reveals unsatisfactory photocatalytic activity due to its rapid electron-hole recombination and large hydrogen evolution overpotential, resulting from lack of driving force for separating photogenerated charge carriers. 13 Additionally, 2D ZIS nanosheets are subjected to easily agglomerate, which greatly constrains their photocatalytic performance. For practical application, it is required to boost the photocatalytic activity and alleviate the aggregation of 2D ZIS nanosheets simultaneously.…”
