文摘

Sb₂Se₃ nanoplates have been synthesized by a solvothermal method in mixtures of tetrahydrofuran and diethylenetriamine at 120?¡ãC with the help of sodium tartrate. The as-prepared samples were determined by means of powder X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and high-resolution TEM (HRTEM). Some experimental parameters influencing the formation of Sb₂Se₃ nanoplates were systematically investigated. Based on the electron microscope observations, a self-assembly process and Ostwald ripening mechanism was proposed for explaining the formation of the Sb₂Se₃ nanoplates. The electrochemical hydrogen storage measurements reveal that the Sb₂Se₃ nanoplates show a high discharging capacity of 237?mA?h?g^?1 at room temperature.
