Protective role against hydrogen peroxide and fibroblast stimulation via Ce-doped TiO2 nanostructured materials
(Elsevier Science, 2016-02)
Background: Cerium oxide (CeO2) and Ce-doped nanostructured materials (NMs) are being seen as innovative therapeutic tools due to their exceptional antioxidant effects; nevertheless their bio-applications are still in their ...
Electro-oxidation of ethanol on PtSn/CeO(2)-C electrocatalyst
(SPRINGER, 2009)
PtSn/CeO(2)-C electrocatalyst was prepared in a single step by an alcohol-reduction process using ethylene glycol as solvent and reducing agent and CeO(2) (15 wt%) and Vulcan XC72 (85 wt%) as supports. The performance for ...
Structural studies of mesoporous ZrO2-CeO2 and ZrO2-CeO2/SiO2 mixed oxides for catalytical applications
(Elsevier Science Sa, 2016-06)
In this work the synthesis of ZrO2-CeO2 and ZrO2-CeO2/SiO2 were developed, based on the process to form ordered mesoporous materials such as SBA-15 silica. The triblock copolymer Pluronic P-123 was used as template, aiming ...
Alcohol induced ultra-fine dispersion of Pt on tuned morphologies of CeO2 for CO oxidation
