Progress on Synthesis and Applications of Cr2O3 Nanoparticles

As is known to us that nanosized chromic oxide (Cr2O3) is an important transition metal oxide. Because it has many excellent properties, it can be used in many fields such as pigment, catalyst, Lithium material etc. This article briefly reviewed the preparation and applications of Cr2O3 nanoparticles. In this paper, some specific applications will be listed according to different fields. Nanosized chromic oxide (Cr2O3) can be obtained via many methods. A summary of the methods have been made. The preparation methods are divided into three main types, including vapor phase method, solid phase method and liquid phase method. Simultaneously, different types of methods have been simply evaluated in this paper. And the advantage and disadvantage are simply noted.
