Fabrication of the SnS2/ZnIn2S4 heterojunction for highly efficient visible light photocatalytic H2 evolution

CdS/ZnIn2S4 type II heterojunctions improve photocatalytic hydrogen production: faster electron–hole separation and wider visible light utilization

“…[14][15][16][17] Among them, ZIS is favored by scientists because of its unique layered structure, suitable band gap, stable physicochemical properties, and low toxicity and low cost. [18][19][20] However, ZIS still has the problems of narrow range of visible light utilization and low efficiency of electron-hole separation in photocatalytic hydrogen production. 21,22 To address these drawbacks, scientists had made some modications.…”

Rational design of 2D/2D ZnIn2S4/C3N4 heterojunction photocatalysts for enhanced photocatalytic H2 production

“…The PL spectra can be used to study separation–recombination properties of photo-induced carriers. 46 The PL of C 3 N 4 , C 3 N 4 (180), ZnIn 2 S 4 , 40ZnIn 2 S 4 /C 3 N 4 and 40ZnIn 2 S 4 /C 3 N 4 (180) are shown in Fig. 4c.…”

Latest Progress on Photocatalytic H2 Production by Water Splitting and H2 Production Coupled with Selective Oxidation of Organics over ZnIn2S4-Based Photocatalysts

“…Therefore, they are separated, and an enhanced photocatalytic activity is thus expected. For example, the performance of the SnS 2 /ZnIn 2 S 4 type-II heterojunction was increased by nearly 10.5 times as compared to the pristine ZnIn 2 S 4 using lactic acid as a hole capturer . ZnIn 2 S 4 can also integrate with MOFs to form a type-II heterojunction to improve HER activity. , For example, the optimal H 2 production rate of the aminated-UiO-66/ZnIn 2 S 4 type-II heterostructure was increased by about 17 times as compared to the pristine ZnIn 2 S 4 under visible light …”
