Comparison of Preparation Methods of Copper Based PGMFree Diesel-Soot Oxidation Catalysts [PDF]

, 2011
CuO-CeO2 systems have been proposed as a promising catalyst for low temperature diesel-soot oxidation. CuO-CeO2 catalysts prepared by various methods were examined for air oxidation of the soot in a semi batch tubular flow reactor. The air oxidation of

Reaction of carboxylic acids on CeO2(111) and CeO2(100)

Catalysis Today, 1996
The reactions of HCOOH and CH3COOH on CeO2(111) and CeO2(100) were studied using temperature programmed desorption (TPD) and high resolution electron energy loss spectroscopy (HREELS). The carboxylic acids were found to dissociate on both surfaces to form carboxylates.

PLXDC2 siRNA-Mediated Intervention Attenuates Microglial Senescence Through cGAS-STING Signaling. [PDF]

Adv Sci (Weinh)
PLXDC2 was identified as a microglial target in Parkinson's disease through human and mouse single‐cell analyses. Ferritin‐armed biomimetic nanovesicles delivered PLXDC2 siRNA, deferoxamine, and CeO2 nanoparticles across the blood–brain barrier, reducing cGAS‐STING activation, iron burden, oxidative stress, and senescence in microglia, thereby ...

Synthesis and Applications of Polymorphic CeO2 and AgI/CeO2 Nanocomposites

Journal of Materials Science: Materials in Engineering
Abstract This paper delves into the innovative synthesis of various morphologies of CeO₂, including flower-like, spherical, quasi-spherical, and rod-shaped, as well as AgI/CeO₂ composites. Utilizing cold coprecipitation and one-pot hydrothermal methods, a range of CeO₂ and highly efficient photocatalytic AgI/CeO₂ composites were successfully ...

Gold catalysts supported on CeO2 and CeO2–Al2O3 for NO reduction by CO

Applied Catalysis B: Environmental, 2006
The reduction of NOx by CO was studied over gold catalyst supported on ceria and ceria-alumina. The mixed supports with different CeO2/ Al2O3 ratios were prepared by co-precipitation. The catalysts were characterized by means of XRD, TPR, XPS and Raman spectroscopy.

CeO2–Al2O3, CeO2–SiO2, CeO2–TiO2 core-shell spheres: formation mechanisms and UV absorption

RSC Advances, 2012
In this work, a general colloid synthesis method for CeO2–Al2O3, CeO2–SiO2, and CeO2–TiO2 core-shell spheres was reported. The properties of these CeO2-based composites were greatly dependent on the additive species. A diffusion-controlled kinetic model was applied to explore the morphology and crystallinity evolution of these core-shell spheres.

Proton Shuttles in CeO2/CeO2−δ Core–Shell Structure

, 2019
A core-shell structure with a CeO2 core and a non-stoichiometry CeO2-d surface layer built up proton shuttles, leading to a super proton conductivity of 0.15 S cm-1 and advanced fuel cell performance, 661 mW cm-2 at 520 ºC. The surface induced conduction
