Nickel sulfide/graphitic carbon nitride/strontium titanate (NiS/g-C3N4/SrTiO3) composites with significantly enhanced photocatalytic hydrogen production activity

Enhanced photocatalytic H2 production over dual-cocatalyst-modified g-C3N4 heterojunctions

“…The above results indicate that the g-C3N4 was successfully co-decorated with Ag and NiS. In addition, no peak shift is observed in the composites, indicating that the crystalline structure of g-C3N4 is not affected by the introduction of Ag and NiS [52,53]. FT-IR spectra of g-C3N4, 1.0-Ag/CN, 10-NiS/CN, and 10-NiS/Ag/CN are presented in Fig.…”

“…All the characteristic peaks related to g-C3N4 are clearly observed for 1.0-Ag/CN, 10-NiS/CN, and 10-NiS/1.0-Ag/CN. No peaks for the bonding of sulfur with other elements are observed, indicating that the sulfur exists mainly as NiS rather than doping the g-C3N4 [52]. Therefore, the results of the FT-IR and XRD analyses demonstrate that the overall structure of g-C3N4 remains intact after loading with Ag and NiS.…”

Visible light-driven photocatalytic activity of wide band gap ATiO3 (A = Sr, Zn and Cd) perovskites by lanthanide doping and the formation of a mesoporous heterostructure with ZnS QDs

“…On the other hand, the efficiency of the photocatalytic degradation of organics by titanates based on alkaline metal ions is low, and achieving maximum degradation efficiency can take several hours due to the fast recombination of electron-hole pairs. 14,19,26 Several strategies such as metal and non-metal doping, 27-29 modification of synthesis methods, [30][31][32][33][34] preparation of heterostructures, [35][36][37][38][39] etc. have been proposed for designing photocatalysts with high performance utilizing visible wavelengths of solar light.…”

Facile One‐Pot Solvothermal Synthesis of Noble Metal‐Free NiS Modified In2S3‐Based Photocatalyst for Highly Efficient Visible‐Light‐Driven Cr6+ Removal

“…NiS emerged as an ultra‐narrow band gap (0.4 eV) electron mediator [57–60] with ultrafast electrons transferring rate, super sunlight absorption ability draws drastic attention in the photocatalytic field and had achieved great progress.…”
