Abstract
Co3O4 nanoparticles of 35 nm with a cauliflower-like morphology were obtained when a monolayer colloidal dispersion of dodecyl sulfate intercalated alpha-cobalt hydroxide in butanol was subjected to solvothermal hydrolytic decomposition. The nanogranular particles exhibit weakly ferromagnetic properties in contrast with both bulk and dispersed nanoparticulate Co3O4.
摘要
当十二烷基硫酸盐插层的α-氢氧化钴在丁醇中的单层胶体分散体进行溶剂热水解分解时，可获得具有菜花状形态的35纳米四氧化三钴纳米颗粒。与块状和分散的纳米颗粒四氧化三钴相比，这些纳米颗粒表现出弱铁磁性。
