This study focused on determining the phytotoxic mechanism of CeO2 nanoparticles (NPs): destroying chloroplasts and vascular bundles and altering absorption of nutrients on conventional and Bt-transgenic cottons. Experiments were designed with three concentrations of CeO2 NPs including: 0, 100 and 500 mg·L(-1), and each treatment was three replications. Results indicate that absorbed CeO2 nanop...

Tuning the interfacial perimeter and structure is crucial to understanding the origin of catalytic performance. This paper describes the design, characterization, and application of CeO2 modified Au@SBA-15 (Au-CeO2@SBA-15) catalysts in selective oxidation of benzyl alcohol. The reaction results showed that Au-CeO2@SBA-15 catalysts exhibited higher catalytic activity compared with Au@SBA-15 and ...

The degradation of a high concentration organic pollutants has long been challenge to water restoration, and the development electro-Fenton catalysis offers practical approach solving this problem. In study, novel catalyst, activated fullerene soot-loaded NiO-doped CeO2 (0.4(0.4NiO-CeO2)-AFS) nanoparticles, was prepared through impregnation 0.4NiO-CeO2 particles soot (AFS). When applied for 200...

cerium oxide (ceo2) or ceria has been shown to be an interesting support material for noble metals in catalysts designed for emission control, mainly due to its oxygen storage capacity. ceria nanoparticles were prepared by precipitation method. the precursor materials used in this research were cerium nitrate hexahydrate (as a basic material), potassium carbonate and potassium hydroxide (as pre...

Nanoscale cerium dioxides with shape of nanoparticles, nanorods, and nanotubes were electrochemically synthesized. The morphology of CeO2 was modulated by changing electrode potential and potential direction. CeO2 nanorods and CeO2 nanotubes were synthesized via the potentiostatic and cyclic voltammeteric methods, respectively. The morphology and structure of the obtained CeO2 were characterize...

YONG, School of Material and Metallurgy, Northeastern University, Liaoning, Liaoning, China In this paper cerium oxide (CeO2) nanoparticles with 200-300 nm in diameter were synthesized via a precipitation method using ammonia water and oxalic acid as precipitant...

Recently, cerium oxide (CeO2) nanoparticles have been widely used in engineering andmedical sciences due to the diversity of their applications. Fe-Ce nanoparticles were synthesized bysimple co-precipitation method via iron nitrate (Fe(NO3)3.9H2O) and cerium nitrate (Ce(NO3)3.6H2O) asprecursor in the presence of cetyltrimethylammonium bromide (CTAB) surfactant. The samples wer...

Solid electrolytes based on doped cerium oxide, Ce(M)O2-δ (M = rare-earth cations), are of considerable interest for potential use in low temperature solid oxide fuel cells (LTSOFCs) due to its higher ionic conductivity than YSZ based solid electrolyte.  In this research work, crystalline, pure Ce1-xMxO2-δ (where M = Gd or Sm, x = 0.10 or 0.20) based nanoparticles were prepared by chemical prec...

In the present work, we have investigated synthesis of cerium oxide nanoparticles (CeO2 NPs) using Curvularia lunata culture filtrate. The synthesized CeO2 NPs were characterized by TG/DTA, XRD, Raman, PL, FTIR, UV-visible spectroscopy and TEM analyses. The synthesized nanoparticles retained the cubic structure, which was confirmed by X-ray diffraction studies. UV-visible spectrum exhibited a w...
