NiS Cocatalyst–Modified ZnIn2S4 as Ohmic‐Junction Photocatalyst for Efficient Conversion of CO2

“…To study the electron separation and transfer performance of the prepared samples, the photoelectrochemical capabilities test was performed on ZnIn 2 S 4 and different mass ratio of ZnIn 2 S 4 –NiS sample. [ 50–52 ] As displayed in Figure 8 a, the TPR intensity decreased in the order of ZnIn 2 S 4 –2%NiS > ZnIn 2 S 4 –5%NiS > ZnIn 2 S 4 –3%NiS > ZnIn 2 S 4 –1%NiS > ZnIn 2 S 4 under simulated sunlight. The results show that NiS plays an important role in charge transfer.…”

“…As displayed in Figure 6b,c, the contact angle of ZnIn 2 S 4 and ZnIn 2 S 4 –2%NiS are 95.7° and 31.5°, respectively, the results show that the prepared ZnIn 2 S 4 –2%NiS composite has excellent hydrophilicity. [ 52,53 ] The previous results show that the prepared ZnIn 2 S 4 –2%NiS has good dispersion in aqueous solution, which provides a good basis for the liquid‐phase photocatalytic reduction of CO 2 .…”

Iodide ions as invisible chemical scissors tailoring carbon nitride for highly efficient photocatalytic H2O2 evolution

“…2.1 Bulk g-C 3 N 4 (BCN) preparation BCN was produced through thermal treatment using melamine as a raw material. 19 Notably, 2.0 g melamine was used as the precursor, and it was put into a porcelain boat. After that, the porcelain boat was put into a muffle furnace for 4 h at 550 °C with a ramp rate of 2.3 °C min −1 .…”

Construction of SnNb2O6/MgIn2S4 heterojunction photocatalysts with enhanced visible-light-driven activity for tetracycline hydrochloride degradation and Cr(vi) reduction

“…[4][5][6][7][8] To date, many kinds of semiconductor materials have been researched and developed to deal with water pollution, including metal oxides, 9,10 sulfides 11,12 and nitrides, 13,14 but most of them are limited by low visible light absorption ability or poor charge separation efficiency. 15 Therefore, the development of new photocatalysts with high photochemical stability and good visible light response is the emphasis of the current water purification research.…”
