Cerium oxide nanoparticles were prepared by a precipitation method using Ce(IV) sulphate as precursor dispersed in glycerol with varying synthesis parameters such as temperature or precipitating agent. The structural and morphological characteristics of the obtained nanoparticles were investigated by X-ray ...
The oxide film of Ce markedly affects its anodic behavior by blocking the dissolution of the underlying metal. Moreover, the dissolution of metal surface brings about the stripping of the oxide film on Ce, thus leading to an oxide free surface. This workdemonstrates a theoretical foundation for...
Subsequently, to remove the exposed metal and metal oxide, the resultant was soaked in 0.5 MH 2 SO 4 for 12 h at ambient temperature, and then washed and dried at 60 C. The obtained product was named as CeC x -NC. 2.3. Characterization The measurements of transmission electron microscopy...
(Fig.1c), respectively19,53. Relative to the standard line patterns of Fe, the diffraction peaks of the constituent FeCo alloy shift to higher angles; while for the CeO2−xNx, the characteristic peaks shift to lower angles compared to those of CeO2. The amount of surface oxide is too ...

In the present studies, renewable and nontoxic biopolymer, pectin, was extracted from Indian red pomelo fruit peels and used for the synthesis of cerium oxide nanoparticles (CeO2-NPs) having bio-therapeutic potential. The structural information of extracted pectin was investigated by FTIR and NMR sp...

The study also highlighted the need to avoid excessive laser power during acquisition of the Raman spectra as this appeared to cause the oxidation of the region being analysed where previously no cerium oxide peak had been detected. The propensity of cerium to oxidise in air results in the ...
