The compositions and morphologies of the products were characterized by XRD, TEM, IR and TG-DTA. The results show that Co(OH)2 nanorods can be obtained only in one-step by means of surfactant-assisted soft-template solid-state chemical reaction method. The surfactant (PEG-400) plays a soft-template like role in the process of Co(OH)2 nanorods formation and leads nanocrystallines to grow along certain direction into nanorods.展开更多

Magnesi um oxalate hollow nanospheres were obtained though grinding directly grinding ma gnesium acetate and oxalic acid. And magnesium oxalate nanorods consisted of hol low nanospheres were also fabricated by means of a suitable surfactant to modify the solid-state reaction mentioned above. The as-prepared samples were characte rized by XRD, TEM and SEM.展开更多
