Name:a>Mesoporous ceria nanoparticles
Product Overview
Cerium (Ce) is one of the most abundant and cheap rare earth elements. Due to its unique 4f electronic structure, CE has been widely used in many fields such as alloy, fluorescence, magnetism and catalysis in recent years. Accordingly, its cerium oxide (light yellow powder) has also attracted great attention. The CeO2 crystal structure is cubic fluorite structure, in which the metal cation (Ce4+) is arranged according to the face-centered cubic lattice, while the anion (O2-) is located in the tetrahedron center. Ce elements usually contain two oxidation states, Ce4+ and Ce3+. When the temperature is very high or in a reducing environment, it can be reduced to CeO2-x (0<x¡ãC.5), resulting in the two valence states can be quickly and reversibly converted to each other, so oxygen vacancy defects are very easy to appear in the lattice of CeO2-x. Due to their inherent oxide defects and excellent REDOX properties and oxygen storage capacity, CeO2 nanoparticles are commonly used as heterogeneous catalysts or active oxide carriers of catalysts.
Mesoporous Ceria Nanoparticles (CeO¡ãCNPs) are nanomaterials with mesoporous structures with pore sizes between 2 and 6 nm. The mesoporous structure provides a large specific surface area and more active sites for various reactions.
