“…However, these metals are always precious and rare, which are limited to their practical application. 21,22 The bimetal sulfides, such as NiMoS, NiCoS, and NiFeS, possess the unique bimetal synergistic effect and tunable potential, resulting in excellent photocatalytic H 2 performance. 23−25 In particular, the transition metals are easy to form an ultrathin lamellar structure due to the metal−sulfur bond, which can provide rich unsaturated active sites in the edges of the S atom.…”

Photocatalysts with hollow structures have drawn great interest owing to their high specific surface area, which can enhance the photocatalytic performance. Herein, we designed the hollow cubic Cu2–x S@Ni–Mo–S nanocomposites by vulcanizing from the Cu2O template and loading the Ni–Mo–S lamellas. The Cu2–x S@Ni–Mo–S composites greatly improved the photocatalytic hydrogen performance. Among them, Cu2–x S–NiMo-5 achieved the optimal photocatalytic rate of 1326.07 μmol/g h, which is approximately 3.85 times higher than that of hollow Cu2–x S (344 μmol/g h) and had good stability for 16 h. The enhanced photocatalytic property was attributed to the metallic behavior of bimetallic Ni–Mo–S lamellas and the LSPR (localized surface plasmon resonance) effect of Cu2–x S. The bimetallic Ni–Mo–S can effectively capture the photogenerated electrons and quickly transfer-diffuse to produce H2. Meanwhile, the hollow Cu2–x S not only provided many more active sites to take part in the reaction but also introduced the LSPR effect to increase the solar utilization. This work provides valuable insights into the synergistic effect of using non-precious metal co-catalysts and the LSPR materials to assist in the photocatalytic hydrogen evolution.

“…Consequently, the hybridization of HT-In 2 O 3 with suitable band-aligned semiconductors can enhance the separation of photoinduced charge carriers and improve the visible-light absorption capacity. This may serve as a proficient tactic for boosting the photocatalytic reduction of small atmospheric molecules. − Nowadays, ternary metal sulfides (M II In 2 S 4 ) with chalcopyrite structures have been extensively evaluated in advanced areas of applications including electrocatalysis, gas storage, thermoelectricity, and photocatalysis. − Mostly, these ternary metal chalcogenides with two-dimensional (2D) sheet-like morphology have received tremendous attention toward photocatalytic applications due to high exposed surface active sites. Thus, the growing of 2D nanosheet-like structures of metals chalcogenide on a hollow tubular substrate is a promising approach to lower the diffusion distance of charge carriers and achieve higher surface exposed active sites. , Hu et al have prepared MOF-derived In 2 O 3 -decorated g-C 3 N 4 photocatalyst by pyrolysis of MIL-68 (In), which shows outstanding efficiency toward photocatalytic H 2 evolution reaction .…”

“…However, the d 0 (CaIn 2 S 4 ) and d 5 (MnIn 2 S 4 ) metal chalcogenides have been rarely examined for photocatalytic reduction of atmospheric molecules.

The rational design of heterojunction photocatalysts is an effective way to improve semiconductor photocatalytic activity. The simple solvothermal method was used to successfully prepare visible light-driven FeIn2S4 microspheres/BiOBr nanoplates binary heterojunction photocatalysts with varying FeIn2S4 contents. The crystal structure, morphology, surface composition, specific surface area, charge separation and optical properties of the as-prepared photocatalysts were investigated using a variety of analytical methods. In the photocatalytic degradation of rhodamine B, the FeIn2S4/BiOBr photocatalysts obtained a degradation efficiency of 96% within 60 min, which was approximately 5.33 and 2.59 times higher than pure FeIn2S4 and BiOBr, respectively. Radical trapping experiments and ESR measurements revealed the main active species (·OH, ·O2−, and h+) produced during photocatalytic degradation. The increased photocatalytic activity was due to the formation of Z-scheme heterojunctions between FeIn2S4 and BiOBr, which contributed to the improved effective charge separation of photogenerated charge carriers, augmented specific surface area and enhanced redox capacity. It is expected that our current study will provide a hopeful way for future environmental remediation research.
