Fabrication and Characterization of Hollow MoS2 Nanospheres

With additive of cetyltrimethylammonium chloride (CTAC), hollow MoS2 nanospheres were prepared via soft template method. SEM, TEM, XRD and EDS were used to Characterize the morphology and phase composition of the final product. The formation mechanism of hollow MoS2 nanospheres was discussed based oil the FTIR spectra of CTAC and the final product. The. results indicate that the product is hollow spheres with diameter of, 30 similar to 100 nm and wall thickness of 10 nm. The crystallinity of the product IS poor, but Call be improved by Calcination. In the formation process of hollow MoS2 nanospheres, CTAC not only acts as the template and scaffold, but also takes part in the chemical reaction with precipitation of intermediate, which results in the preliminary formation of the core-shell Structure.
