沉淀法制备纳米CeO_2粒子的化学原理及影响因素研究

Study of Chemical Principles and Influening Factors of Preparing CeO_2 Nanoparticles by Precipitation Process

介绍了沉淀法制备纳米CeO2粒子的化学原理,重点讨论了在纳米CeO2的制备过程中,反应温度、反应浓度、表面活性剂、pH值、反应时间(陈化)、加料方式等因素对粒子大小、形貌的影响。

In this paper, chemical principles of precipitation process of CeO2 nanoparticles are systematically introduced. The effects of the operation parameters on the nanoparticles size and its appearance, such as the reactant concentration, temperature, pH value, time and surfactant are discussed.
