【Abstract】 A mild biomolecule-assisted route were developed to synthesize Cu3SbS3 nanorods under solvothermal conditions at 200 ℃ for 12 h,using CuCl2 as copper source,SbCl3 as antimony source and L-cystine was used as the sulfide source and complexing agent.The paper explored the influence of the reaction temperature and time on the phase composition,morphology and structure of the as-prepared Cu3SbS3 products.The products were characterized by XRD,SEM,EDS,HRTEM,SAED,etc.The results reveal that the as-synthesized Cu3SbS3 nanorods have diameters ranging from 100 to 150 nm and lengths up to several micrometers.A possible formation mechanism for Cu3SbS3 nanorods was also discussed.更多还原
