“…Recently, the two‐dimensional MoS 2 has attracted many interests in PHE to replace the expensive noble metals [14] . Moreover, many reports demonstrated that MoS 2 is an eﬀective co‐catalyst to realize the enhanced PHE activity under visible light irradiation [15–17] . Various theoretical and experimental results proved that unsaturated S atoms located along the edges of the MoS 2 layers were catalytically active for PHE, while the S atoms on the basal plane exhibited no activity [18–20] .…”

The construction of the heterostructures with intimate contacts and prominent sunlight absorption capacity are essential for achieving the highly effective photocatalytic H2 evolution. Here, the CdS/MoS2 heterostructures constituted by CdS nanoparticals loaded on uniform MoS2 nanoribbons were synthesized through solid‐gas reaction and hydrothermal treatments. In the as‐prepared CdS/MoS2 heterostructures, there are large‐area contact interfaces between the external highly dispersed small CdS nanoparticals and MoS2 nanoribbons. Impressively, the optimized CdS/MoS2‐8 photocatalyst delivered the highest hydrogen production rate of 91.2 μmol h−1, which is 9 times that of CdS. It demonstrates that the formation of the heterostructures could eﬀectively promote the separation and transfer of photogenerated charge carriers due to the intimate contacts between CdS nanoparticals and MoS2 nanoribbons. This work would provide a new method to develop efficient photocatalysts for photocatalytic H2 evolution.

“…The CB of In 2 O 3 (~ − 0.6 eV versus SHE) being more negative than that of MoS 2 (~ − 0.5 eV versus SHE), there was a migration of photogenerated electrons from the CB of In 2 O 3 to that of MoS 2 following which there occurred interaction of these electrons with adsorbed O 2 species to form O 2 −· 46 , 47 . With a band gap of 1.91 eV, the VB of MoS 2 (~ + 1.39 eV versus SHE) would be placed higher than that of In 2 O 3 (∼ + 2.2 eV versus SHE) 52 , 53 . This would drive holes from the VB of In 2 O 3 to that of MoS 2 .…”

The current work involves synthesis of hybrid nanomaterial of In2O3/MoS2/Fe3O4 and their applications as photocatalysts for disintegration of esomeprazole under visible light illumination. The data emerged from various analyses testified to the successful construction of the desired nano-scaled hybrid photocatalyst. Tauc plot gave the band gap of In2O3/MoS2/Fe3O4 to be ~ 2.15 eV. Synergistic effects of the integrant components enabled efficacious photocatalytic performances of the nanocomposite. The nanohybrid photocatalyst In2O3/MoS2/Fe3O4 showed photodecomposition up to ~ 92.92% within 50 min. The current work realizes its objective of constructing metal oxide based hybrid nano-photocatalyst supported on MoS2 sheets for activity in the visible spectrum, which displayed remarkable capacity of disintegrating emerging persistent organic contaminants and are magnetically recoverable.

Photocatalytic nitrogen fixation and pollutants degradation at ambient temperature and pressure as a clean and efficient means represents a sustainable direction. In this paper, novel two-dimensional (2D) ZnIn2S4/2D BiOCl (ZIS/BOC) nanosheets heterostructures were successfully synthesized by in-situ solvothermal techniques. XPS and TEM results showed the formation of heterostructure. The photocatalytic properties of these materials were further studied by degradating phenol and nitrogen fixation under visible light irradiation. In particular, heterostructure obtained with a mass ratio of 0.5 wt % of ZnIn2S4 had a good application prospect and can achieve 77.4% phenol degradation rate within 6 h and a rate of ammonium production of 14.6 µmol∙gcat−1·h−1. The reaction rate of 0.5 wt % ZIS/BOC heterostructure exhibited 8.6 and 2.6 times relative to BiOCl for the degradation of phenol and nitrogen fixation, respectively. The enhanced photocatalytic activity was attributed to the collaboration of low recombination rate of photo-generated carriers and enhanced visible light absorption. Based on capture experiments and electron spin resonance (ESR) techniques, the main active species that may appear in photocatalytic systems were explored, and the corresponding photocatalytic mechanism was also proposed appropriately. This strategy will open up new ideas for the design and manufacture of more energy-efficient materials with high photocatalytic activity.
