Design of optical characteristics of ceria nanoparticles for applications including gas sensing and up-conversion
… and structural characteristics of cerium oxide (ceria) nanoparticles synthesized using chemical precipitation. The dopants selected are samarium and neodymium, which have positive association energy with oxygen vacancies in the ceria host, and negative association lanthanides, holmium and erbium, …

Colloidal Cerium Oxide Nanoparticle: Synthesis and Characterization Techniques
… CeO2 is the stable form of bulk cerium oxide, ceria nanoparticles exhibit a nonstoichiometric composition, CeO2-γ, due to the presence of oxygen vacancies and the formation of Ce2O3 at the grain boundaries. The Ce(III) ions, which are more reactive and therefore more desirable for various …

Investigation of Ni-Ceria Nanocatalysts: Improved Computational Methods Towards Hydrogen Production in Aquaprocessing of Heavy Oil
Ni-Ceria (Ni-CeO2) nanoparticles (NPs) are promising nanocatalysts for water splitting and water gas shift reactions due to the ability of ceria to temporarily donate oxygen to the catalytic reaction and accept oxygen after the reaction is completed. Therefore, elucidating how different properties …
