Cerium oxide nanoparticles: size-selective formation and structure analysis. Appl. Phys. Lett, 80, 127Zhang, et al., Cerium oxide nanoparticles: size selective formation and structure analysis, Applied Physics Leters, 2002, pp. 127-129, vol. 81, No. 1....
This led to the formation of cerium oxide supported on TiO2 (Ce/TiO2). Meanwhile, 3.93 mmol of NH4VO3 (Junsei, ≥ 99.0%) and 3.93 mmol of C2H2O4 (oxalic acid, Junsei, ≥ 99.5%) were dissolved in 50 mL of de-ionized H2O, whereas 1.64 mmol of Sb(CH3COO)3 (Alfa ...
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...
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 ...
Keywords: Ce-Fe complex oxide; silicone rubber; thermal oxidative stability; radical; thermal aging 1 Introduction Silicone rubber (SR) has attracted great attention for its high thermal oxidative stability, which can maintain good performance at 250°C for a long time. However, with the advancemen...
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...

Raman band at ~590 cm−1, which is assigned to theEgof CoFeOOH53. The weak Raman signal at ~590 cm−1indicates that there only forms an ultrathin CoFeOOH layer on the surface of nanoporous FeCo alloy/oxide ligaments, which is conducive to their electron transportation from ...

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 ...
