摘要：

Bismuth sulfide (Bi(2)S(3)) nanoflowers and nanorods were synthesized by thermal decomposition of single source precursor, bismuth di-n-octyl-dithiophosphate (Bi[S(2)P(OC(8)H(17))(2)](3)), in an ionic liquid (IL) solvent. Both of these products belong to the orthorhombic phase by the analysis of the X-ray powder diffraction spectra. The morphology evolution of Bi(2)S(3) from nanoflowers to nanorods was investigated based on transmission electron microscopy observations. The electrochemical hydrogen storage behavior of these Bi(2)S(3) nanostructures was studied in detail. It was found that the morphology and structure played an important role on the hydrogen storage capacity of such nanomaterials. The Bi(2)S(3) nanoflower structures have a discharging capacity of 100 mAh g(-1) at room temperature, which makes it a potential candidate for applications in hydrogen storage, high-energy batteries, and catalytic fields.
