Due to its excellent physicochemical properties, cerium oxide (CeO2) has attracted much attention in recent years. CeO2 nanomaterials (nanoceria) are widely being used, which resulted them getting released the environment, and exposure humans (mostly via inhalation) is a major concern. In present study, nanoparticles were synthesized by hydroxide-mediated method further characterized Scanning E...

In the present study, a conversion layer mainly composed by cerium oxide was prepared by means of a novel ultrasound-assisted coating process. The formation of a conversion layer on top of the Mg alloy provides physical barrier properties improving the corrosion protection. In addition, the incorporation of cerium oxide within the coating enables the formation of a protective layer on the pores...

Nanocrystalline cerium oxide is an attractive material for catalysis of environmentally hazardous gas-phase species such as sulfur dioxide and carbon monoxide. Oxygen vacancies in cerium oxide are believed to coordinate and aid in the transfer of oxygen ions between the reactive species. We have sought to characterize these defects in nanocrystalline cerium oxide as a function of the heat treat...
