Several main preparation methods of nano-CeO2and their research progress are reviewed. The advantages and disadvantages of three major methods including gas phase, solid phase and liquid phase are analyzed and com- pared separately. Sample prepared by gas phase method has high purity and small reunion, but the expensive equipment makes it difficult to popularize. Liquid phase method is easy to popularize, but its sample has heavy reunion. The solid phase method has outstanding merits of simple production process and low pollution, while the uniformity of sample which prepared via this method is hard to control. The future directions of the preparation methods of nano-CeO2are analyzed and prospected too.
