摘要
High-surface-area porous MoS2 was successfully synthesized through a sol-gel route using (NH4)(2)Mo3S13 as precursor. A novel molybdenum polysulfide gel "Mo3S12" was firstly prepared through the reaction of (NH4)(2)Mo3S13 formamide solution with hydrochloric acid solution. Subsequently, the porous MoS2 was obtained from the "Mo3S12" gel by ethanol supercritical drying technique. X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), nitrogen physisorption measurement (BET) were used to characterize the porous MoS2 samples. The results indicated this porous MoS2 has a broad range of pore sizes and a BET surface area of 315 m(2)/g and a pore volume of 1.9 cm(3)/g. (C) 2012 Elsevier B.V. All rights reserved.
