Preparation and improved photocatalytic activity of mesoporous WS 2 using combined hydrothermal-evaporation induced self-assembly method
Source abstract
Abstract
Abstract In this paper, we report mesoporous WS 2 nanosheets with a crystalline network that were synthesized using CTAB as a structure-directing agent via self-assembly induced by hydrothermal and thermal evaporation. Powder X-ray diffraction, Raman spectra, and high-resolution X-ray photoelectron spectroscopy results confirmed the formation of WS 2 structures. Scanning electron microscopy and transmission electron microscopy were used to observe the as-prepared mesoporous frameworks. The mesoporous WS 2 nanosheets have a surface area of 197 m 2 g −1 . A possible growth mechanism is reported for these mesoporous WS 2 nanosheets. The mesoporous WS 2 nanosheets demonstrate high photocatalytic activity. Among different concentrations, 0.1 wt% mesoporous WS 2 shows superior catalytic activity compared to pristine WS 2 nanosheets.
