Preparing ultra-fine ZrO2 fiber with high quality is the key to realize its application in catalysis, energy and environment area, etc.. Electrospinning technology is a newly developed method in recent years for preparing oxide ceramic nanofibers. ZrO2 nanofibers prepared by electrospinning exhibit many unique properties such as small diameters, good uniformity, high surface area and good continuity. Moreover, the composition and properties of the nanofibers can be easily controlled by varying the spinning solution, electrospinning parameters and heat treatment process. The preparation, the microstructure tailoring and the properties of ZrO2 nanofibers are discussed. The highlights of some recent applications of the electrospun ZrO2 nanofibers are also provided, including catalysis, energy technology, and environment, etc..
