| Abstract: | Nano nickel selenides with octahedral morphology were successfully synthesized via a simple mild solvothermal method.In the process,glycol was used as both solvent and reducing agent.The as-synthesized nano-sized nickel selenide was characterized by SEM,XRD,TEM,and so on.The investigation indicated that the formation of the octahedral NiSe was strongly dependent on the reaction temperature and time.Interestingly,it was found that the as-prepared octahedral NiSe showed efficient catalytic performance for decomposition of hydrazine hydrate at room temperature. |
