Recently, the Modern Analysis and Gene Sequencing Center published a review article titled "Unraveling the physical chemistry and materials science of CeO2-based nanostructures" in the international authoritative journalChem. The paper systematically summaried the development of application of the various high-end in-situ testing technologies of TEM/XRD/XPS/IR/Raman/ in revealing the active centers of CeO2-based catalytic materials. The first author of the paper is Dr. Zhang Yang from the Modern Analysis and Gene Sequencing Center, and the co-corresponding authors are Academician Zhang Hongjie and Researcher Song Shuyan from the Changchun Institute of Applied Chemistry of Chinese Academy of Sciences. Zhengzhou University is the first author.
