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.

“…The magnetization value at room temperature is obviously higher than the reported ZnFe 2 O 4 nanomaterials through hydrothermal synthesis [33]. The magnetic nature of the ZnFe 2 O 4 nanoparticles enables trouble-free separation of the sample from the mixture using an external magnet, which can eliminate the necessity of filtration and centrifugation [34].…”

a b s t r a c tZnFe 2 O 4 nanoparticles with diameter of ca.10 nm were successfully synthesized under hydrothermal conditions without using any surfactant or structure-directing agents. The structure, composition and morphology of the samples were characterized by means of powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (SEM), transmission electron microscopy (TEM), diffuse reflectance spectra (DRS) and the Brunauer-Emmett-Teller (BET) surface area measurement. The results showed that the mole ratio of reactants ZnO to FeCl 3 played an important role in controlling the composition and morphology of the products. BET specific surface area of ZnFe 2 O 4 nanoparticles was evaluated to be 115.6 m 2 g −1 . Interestingly, as-prepared ZnFe 2 O 4 nanoparticles displayed enhanced gas sensing performance to acetone, which response value reached 39.5 for 200 ppm acetone gas at lower optimum working temperature of 200 • C, in comparison with the precursor ZnO (4.2) at the same condition. The gas sensing property demonstrates that as-prepared ZnFe 2 O 4 has potential applications in the detection of acetone.
