Structural, Optical, and Magnetic Properties of Nd-Doped CeO2 Nanoparticles Codoped with Transition Metal Elements (Cu, Zn, Cr)

Nanostructured CeO2 Thin Films Prepared by the Sol-Gel Dip-Coating Method with Anomalous Behavior of Crystallite Size and Bandgap

“…Besides, the application of ferromagnetic semiconductor and oxides as the material base for spintronics has stimulated the search of these types of materials. Recent works report that strain induces ferromagnetism in semiconductors and oxides [23], such is the case of ferromagnetism induced in Nd-doped CeO 2 nanoparticles due to VOs provoked by the doping [24].…”

Investigation of structural, optical, and magnetic properties of Nd‐doped Sr2SnO4 Ruddlesden Popper oxide

“…Ferromagnetism in Gd‐doped CeO 2 is explained by interaction between Ce 3+ ‐Ce 4+ through superexchange mediated via oxygen vacancy 45 . Presence of oxygen vacancy in various oxide ceramics doped with transition metal gives ferromagnetism that mediates either by double‐exchange or superexchange mechanism 10,46‐50 . In present case, there are two kinds of interactions that are possible with doping of Nd; first one is and second one is .…”

Hydrothermal synthesis and characterization of transition metal (Mn/Fe/Cu) co-doped cerium oxide-based nano-additives for potential use in the reduction of exhaust emission from spark ignition engines

“…As a result of the transition elements' signicant oxidative properties combined with oxygen storage materials such as CeO 2 , the resulting mixed oxide acts as an extremely efficient and inexpensive catalyst for oxidation reactions. [17][18][19][20] Recently, Jampaiah et al asserted that the enhanced catalytic performance of copper and manganese doped cerium oxide is due to the production of more Ce 3+ species or oxygen vacancies (V o ) in the ceria lattice due to the dopant insertion. Furthermore, Yang et al demonstrate that copper doped CeO 2 has improved catalytic activity due to increased surface oxygen defects in the cerium oxide lattice structure caused by the substitution of Ce 4+ ions with Cu dopant.…”

“…Transition metals such as Mn, Fe, Cu have been chosen as possible co-dopants to improve the structural, surface, and redox properties of cerium oxide catalysts. [15][16][17][18][19][20][21][22] As a result, we synthesized transition metal co-doped CeO 2 catalysts, such as Mn/Fe-CeO 2 , Mn/Cu-CeO 2 , Fe/Cu-CeO 2 and Cu/Ag-CeO 2 by a hydrothermal approach and examined their efficacy in reducing exhaust emissions from spark ignition (SI) engines. The synthesised nano-catalysts were characterised using a variety of techniques, including X-ray diffraction (XRD), RAMAN spectroscopy, X-ray absorption studies (XAFS), X-ray absorption near edge spectroscopy (XANES), extended X-ray absorption ne structure (EXAFS), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), Brunauer-Emmett-Teller (BET) and UV-diffuse reectance spectroscopy.…”
