Well-defined Sb2S3 microspheres: High-yield synthesis, characterization, their optical and electrochemical hydrogen storage properties

Well-defined Sb2S3 microspheres consisted of many small nanoparticles were synthesized via a simple one-pot hydrothermal process. On the basis of a series of contrast experiments, the probable growth mechanism and fabrication process of the products were proposed. The optical properties of the products were studied as well and the results demonstrated that the products presented blue luminescence related to the corresponding microstructure. In addition, we firstly verified that the Sb2S3 microspheres could store hydrogen electrochemically, and a discharge capacity of 101 mA h g(-1) was measured under normal atmosphere at room temperature.
