Preparation of bimetallic oxide nanomaterials progresses

The research group led by Shanghai Institute of Ceramics, Chinese Academy of Sciences, has recently developed a simple method that is important for the preparation of bimetallic oxide nanomaterials. By controlling the experimental conditions, a ferromagnetic material is obtained at a relatively low temperature. Co-Sn-O nanorods, nanorings. The research group also studied the formation mechanism of the Co-Sn-O nanorings, and believed that the interdiffusion between the two oxides is the main reason for forming the nanoring structure.

At present, the preparation and performance research of nanomaterials has become a global research hotspot, and the development of high-performance nano-functional materials has become the primary task in the field of materials science. Bimetal oxides are a large class of important functional materials and have many important applications in gas sensors, functional devices and other fields. However, conventional methods for preparing bimetal oxides, such as solid-phase reaction and sol-gel methods, require higher calcination temperatures and are not conducive to obtaining nanostructured materials.
