Synthesis of Cobalt Sulfide Nanocrystallites via an Efficient Microwave Hydrothermal Process

摘要：

　　Nanostructured cobalt sulfide(CoS) can be widely used as high energy density batteries,supercapacitors,solar photovoltaic materials and catalysts due to its excellent electronical,optical,magnetic and catalytic performance.In order to synthesize CoS crystallites in a efficient route,a facile microwave hydrothermal process was developed by using cobalt nitrate hexahydrate and thioacetamide(TAA) as source materials.The phase compositions and morphologies of the crystallites were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM).The influences of microwave hydrothermal temperature and time on the phase,grain size and morphology of the CoS nanocrystallites were particularly investigated.Our experiment shows that CoS crystallites can be obtained at the hydrothermal temperature of 180 ℃.The as-synthesized CoS nanocrystallites are hexagonal phase with the grain size of 10~30 nm.With the increase of hydrothermal time,both the increase of particle size and the growth of (102)-orientation are obviously.
