摘要
从相态的角度概述了制备纳米γ-Fe2O3的各种方法:固相法、气相法-激光加热法、液相法(化学沉淀法、空气氧化法、溶胶-凝胶法、微乳液法、电化学法)的研究进展。阐述了各种方法的制备原理、特点及应用,介绍了制备纳米-γFe2O3的一些其它方法。并对纳米-γFe2O3的研究方向进行了展望。
From the point of view of phase, the methods of preparing nano-γ-Fe2O3 are summarized in this paper. Those methods include solid-phase synthesis, gas-phase synthesis (laser pyrogenation) and liquidphase synthesis. And liquid-phase synthesis includes chemistry precipitation, air oxidation, sol-gel, microemulsion and electrochemistry. The preparing principle, characteristic and application of every method are presented. Some other methods of preparing nano-γ-Fe2O3 are introduced. Furthermore, research direction of nano-γ-Fe2O3 is expected.
