摘要
A hydrothermal reaction route has been developed to prepare chalcopyrite phase CuFeS2 nanorods at 200-250 degrees C. X-ray powder diffraction and transmission electron microscopy results reveal that the CuFeS2 synthesized displays nanorods with diameters of 20-40 nm and lengths of up to several micrometers. Elemental analysis gives the atomic ratio of Cu:Fe:S of 1:1.04:2.11. The Fe-57 Mossbauer spectrum exhibits a six-peak hyperfine magnetic spectrum and a like-splitted line non-magnetic peak. The factors influencing the formation of the CuFeS2 nanorods were discussed.
