Title: Solid-phase reaction synthesis of mesostructured tungsten disulfide material with a high specific surface area

Abstract

Highlights: {yields} WS{sub 2} material was synthesized through solid-phase reaction. {yields} (NH{sub 4}){sub 2}WS{sub 4} as precursor and n-octadecylamine as template. {yields} WS{sub 2} material has high specific surface area (145.9 m{sup 2}/g). {yields} The whole preparation process is simple, convenient, green and clean. -- Abstract: A mesostructured tungsten disulfide (WS{sub 2}) material was prepared through a solid-phase reaction utilizing ammonium tetrathiotungstate as the precursor and n-octadecylamine as the template. The as-synthesized WS{sub 2} material was characterized by X-ray powder Diffraction (XRD), Low-temperature N{sub 2} Adsorption (BET method), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM). The characterization results indicate that the WS{sub 2} material has the typical mesopore structure (3.7 nm) with a high specific surface area (145.9 m{sup 2}/g), and large pore volume (0.18 cm{sup 3}/g). This approach is novel, green and convenient. The plausible mechanism for the formation of the mesostructured WS{sub 2} material is discussed herein.
