The stability of AuCu, Au2Cu, AuCu2, Au2Cu2, and Au3Cu clusters on the CeO2(110) surface is related to favourable interaction between theAu Cu d-orbitals with theO p-orbitals surface. On most stable AuCu/CeO2(110) systems, two Ce(IV)-ions are reduced Ce(III)-ions however, relatively lesser triatomic AuCu2 cluster can reduce up three Ce(IV)-ions. non-interacting Au-atoms in Au2Cu/CeO2(110) Au3Cu...

OBJECTIVE Cerium oxide (CeO2) nanoparticles have been shown to protect cells in culture from lethal stress, but no protection in vivo has been reported. Cardiac-specific expression of monocyte chemoattractant protein (MCP)-1 in mice causes ischemic cardiomyopathy associated with activation of endoplasmic reticulum (ER) stress. The aim of this study was to assess the effects of CeO2 nanoparticle...

This paper reports the synthesis of CeO2/ZrO2 nanocomposite by wet chemical method using cationic surfactant (CTAB). The properties of the obtained nanocomposites were analysed by X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscoy (SEM), transmission electron microscopy (TEM), UV-Diffuse Reflectance Spectroscopy (UV-DRS) and photoluminescence (PL) spectrosco...

Ni enhanced CeO2 based catalysts were tested in CO2 hydrogenation reaction with the objective to investigate importance and role of Ni0 Ni0-NiO-CeO2−x interfaces. Two materials prepared: a 4 mol% NiO/CeO2 interfacial oxide where supports NiO nanoparticles was produced by wet impregnation method Ce0.96Ni0.04O2 mixed obtained co-precipitation Ce3+ Ni2+ ions. Besides these materials, pure also syn...

A low-concentration cobalt (∼6 at%) and manganese (∼3 at%) bimetallic oxide catalyst supported on ceria nanorods (CoMnOx/CeO2), as well as its related single metal oxide counterparts (CoOx/CeO2 and MnOx/CeO2) was synthesized via a deposition-precipitation approach. The fresh samples after air-calcination at 400 °C were tested under the reaction conditions of CO oxidation, and showed the followi...

Water gas shift reactions (WGS) were evaluated over Ni/CeO2 and Ni/CeSmO catalysts for hydrogen production. The effects of catalyst preparation method Sm loading investigated. Ni/ceria synthesized by combustion, sol gel gel-combustion method. After WGS tests, the determined carbon deposition thermogravimetric analysis. analysis temperature programmed NH3 desorption showed that addition promoter...
