The phase purity and crystal structure of as-synthesized CeO 2 nanocrystals are characterized by XRD pattern (Figure 4).All the distinguishable peaks correspond to the (111), (200), (220), (311), (222), and (400) planes of a cubic fluorite structure (space group: Fm3m) of CeO 2 as identified using …
WebWe report room temperature ferromagnetism in Ni doped CeO2 nanoparticles using X-ray diffraction (XRD), high resolution transmission electron microscopy (HR-TEM), and dc magnetization measurements. Nanoparticles of Ce(1-x)Ni(x)O2 (0.0 < or = x < or = 0.10) were prepared by using a co-precipitation method. WebIn particular, the electronic structure of IrO 2, with d orbitals that might localize but also participate in bonding, makes it dramatically different from normal metals. Although IrO 2 bonds have considerable covalent character, it is a reasonable approximation to consider the O atoms as O 2– and the Ir atom as Ir 4+.
