“…The fringes spacing of 0.35 nm is corresponding to the (101) plane of the anatase TiO 2 [16]. On the other hand, the spacing of a few layer MoS 2 sheets was observed and measured as 0.75 nm, which is in accordance with the reported value [8]. The selected area electron diffraction (SAED) in Fig.…”

“…Layered MoS 2 has been deposited on TiO 2 nanobelts, nanofibers and nanoclusters to enlarge the light absorption and improve the performance of photocatalytic hydrogen generation and photodegradation of hazardous organic pollutants [6][7][8]. Hollow TiO 2 sphere has been reported with superior photocatalytic activity because of the relatively large surface area compared with nanoparticle [7].…”

a b s t r a c tMultilayered MoS 2 coated hollow TiO 2 heterostructures were fabricated by a two-step hydrothermal process using TiO 2 hollow spheres as precursors. Compared with pure TiO 2 , the heterostructures exhibited greatly enhanced visible-light-responsive activity on photodecomposition of colorless phenol, due to the enlargement of visible light absorption and improvement separation efficiency of photogenerated electron-hole pairs. Photocatalytic activity was influenced by the MoS 2 /TiO 2 ratio and the optimized composition was obtained with high stability during recycling.

“…However, MoS 2 nanosheets easily aggregate owing to their high surface energy, which results in deteriorated catalytic activity and stability. One effective solution is to load MoS 2 nanosheets with support materials [15] such as carbon nanotubes [16], graphene [17], porous metals [18], or TiO 2 nanofibers [19].…”

Emerging hierarchical MoS 2 /pillared-montmorillonite (MoS 2 /PMMT) hybrid nanosheets were successfully prepared through facile in-situ hydrothermal synthesis of MoS 2 within the interlayer of cetyltrimethylammonium bromide PMMT, and their catalytic performance was evaluated by the reduction reaction of 4-nitrophenol (4-NP) using NaBH 4 as a reductant. Microstructure and morphology characterization indicated that MoS 2 /PMMT exhibited hybrid-stacked layered structures with an interlayer spacing of 1.29 nm, and the MoS 2 nanosheets were intercalated within the montmorillonite (MMT) layers, with most of the edges exposed to the outside. The catalytic activity and stability of MoS 2 /PMMT were both enhanced by the MMT. With the MoS 2 /PMMT as the catalyst, the apparent reaction rate constant of the 4-NP reduction was 0.723 min −1 and was maintained at ~0.679 min −1 after five reaction cycles. The structural evolution of MoS 2 /PMMT and the possible catalysis mechanism for the reduction reaction of 4-NP were investigated. The as-prepared MoS 2 /PMMT hybrid nanosheets are promising candidates for catalytic application in the water-treatment and biomedical fields. The strategy developed in this study can provide insights for designing hybrid nanosheets with diverse heterogeneous two-dimensional (2D) nanomaterials.

“…MoS2, a transitional metal dichalcogenides semiconductor with an indirect band gap of about 1.3 eV, exhibits p-type properties and has been used for modifying other semiconductor photocatalysts [37][38][39][40][41]. The TiO2@MoS2 heterostructure achieved high photocatalytic hydrogen production, which resulted from the positive synergetic effect between the MoS2 and TiO2 [42]. Improvement in UV light photocatalytic activity has been observed for MoS2/Bi2O2CO3 composites as well, but no research about the enhanced visible photocatalytic activity for MoS2/Bi2O2CO3 is studied [43].…”
