“…This study might provide some interesting insights into designing and constructing visible-light-responsive photocatalyst composites for realizing enhanced solar-to-hydrogen conversion efficiencies. Additionally, it is known that the localized surface plasmon resonance (LSPR) in several metals (e.g., Au, Ag, Cu, and Bi) [371][372][373][374][375][376][377][378][379][380][381][382][383] and nonmetal compounds (e.g., W18O49 and MoxW1-xO3-y) [384][385][386][387][388] could be used to sensitize wide bandgap semiconductors and achieve visible-light or NIR photocatalysis. Therefore, combining plasmonic materials and Ni-based cocatalysts should be an interesting strategy to boost visible-light H2 production.…”

Photocatalysis is believed to be one of the best methods to realize sustainable H2 production. However, achieving this through heterogeneous photocatalysis still remains a great challenge owing to the absence of active sites, sluggish surface reaction kinetics, insufficient charge separation, and a high thermodynamic barrier. Therefore, cocatalysts are necessary and of great significance in boosting photocatalytic H2 generation. This review will focus on the promising and appealing low-cost Ni-based H2-generation cocatalysts as the alternatives for the high-cost and low-abundance noble metal cocatalysts. Special emphasis has been placed on the design principle, modification strategies for further enhancing the activity and stability of Ni-based cocatalysts, and identification of the exact active sites and surface reaction mechanisms. Particularly, four types of modification strategies based on increased light harvesting, enhanced charge separation, strengthened interface interaction, and improved electrocatalytic activity have been thoroughly discussed and compared in detail. This review may open a new avenue for designing highly active and durable Ni-based cocatalysts for photocatalytic H2 generation.

“…However, isolated CaIn 2 S 4 has limited large-scale applications toward photocatalysis, which is especially due to the high rate of recombination of photogenerated electron–hole charge carriers as well as low separation efficiency . Thus, it was later combined with different metal oxides (CaIn 2 S 4 /TiO 2 and CaIn 2 S 4 /Ag 3 PO 4 ), , novel metals (Au-Pt alloy/CaIn 2 S 4 , Au/CaIn 2 S 4 , and Au-Cu/CaIn 2 S 4 ), − layered materials (CaIn 2 S 4 /g-C 3 N 4 and CaIn 2 S 4 /RGO), , and carbon materials (CNTs/CaIn 2 S 4 ), but its hydrogen evolution rate is not comparable with those of the other known efficient metal sulfides. Thus, it is most challenging for ternary metal chalcogenides to achieve better improvement in photocatalytic H 2 production, but this can be mitigated by coupling CIS with other semiconductors, such as two-dimensional (2D) layered metal dichalcogenides.…”

Fabrication of Hierarchical Two-Dimensional MoS₂ Nanoflowers Decorated upon Cubic CaIn₂S₄ Microflowers: Facile Approach To Construct Novel Metal-Free p–n Heterojunction Semiconductors with Superior Charge Separation Efficiency

Due to the enormous demand for effective conversion of solar energy and large-scale hydrogen production, cost-effective and long-lasting photocatalysts are believed to be necessary for global production of sustainable and clean hydrogen fuel. Robust and highly efficient p-n heterojunction photocatalysts have a striking ability to enhance light-harvesting capacity and retard the recombination of photoexcitons. A series of p-MoS/n-CaInS heterojunction composites with different MoS contents have been synthesized via a facile two-step hydrothermal technique in which rose-like p-MoS nanoflowers are decorated upon n-type cubic CIS microflowers. In the synthesis protocol highly dispersed MoS nanoflowers provided more active edge sites for the growth of c-CIS nuclei, leading to a hierarchical architecture with intimate interfacial contact. The formation of a hierarchical flower-like morphology of the photocatalyst has been established by an HRTEM and FESEM study. Electrochemical characterization, especially the slope of the curve from Mott-Schottky analysis and nature of the current from LSV, reveals the p-n heterojunction nature of the composite photocatalyst. The fabricated heterojunction photocatalysts were further examined for visible light photocatalytic H evolution. Far exceeding those for the neat c-CIS and MoS, it is seen that the p-MoS/n-CIS heterojunction photocatalyst with an optimum content of MoS exhibited enhanced H evolution using a 0.025 M NaS/NaSO solution as hole quenching agent under visible light illumination. The 0.5 wt % p-MoS/n-CIS photocatalyst presents a higher H production rate of 602.35 μmol h with 0.743 mA cm photocurrent density, 19 times and 8 times higher than those of neat c-CIS, respectively. This superior photocatalyic activity is due to the efficient separation of electron-hole charge carriers at the interface, as supported by a photoluminescence study and EIS measurements.

“…The CaIn2S4 belongs to the AB2X4 semiconductor family. They possess suitable band edge positions (Li et al, 2017), high chemical stability (Liu et al, 2019), and narrow bandgaps (Wan et al, 2018), which make them more effective in the photocatalysis field due to their multiple potential applications (Ding et al, 2014;Jo and Natarajan, 2015;Li et al, 2017;Liu et al, 2019).…”
