The effect of the calcination conditions on the catalytic activity for N2O decomposition of 2.5% RhOx/CeO2 catalysts has been investigated. Ramp and flash calcinations have been studied (starting calcinations at 25 or 250/350 °C, respectively) both for cerium nitrate and ceria-impregnated rhodium nitrate decomposition. The cerium nitrate calcination ramp has neither an effect on the physico-che...

Abstract A novel modified electrode based on cerium vanadate and copper tungstate (CeVO 4 -CuWO ) nanocomposite was prepared as a sensitive sensor for the methyldopa. The characterized by x-ray diffraction (XRD), energy dispersive spectroscope (EDX), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) methods. cyclic voltammetry (CV) differential pulse (DPV) tech...

The promotion of Ag–ZSM-5 by cerium for the selective catalytic reduction (SCR) of NO with methane in the presence of an excess of oxygen was studied in this work. Ce–Ag–ZSM-5 catalyzes the CH4-SCR of NOx over the temperature range of 450–600◦C. Rate measurements of NO reduction to N2 under SCR conditions and of the competing CH4 oxidation by O2 (CH4 combustion) show that incorporation of a sma...

Calcium fluoride nanoparticles with special amount of cerium ion (%1) were synthesized by coprecipitation. Fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD), absorption and photoluminescence (PL) from CaF2Ce nanoparticles has been investigated. FTIR spectra reveal that there are some amounts of OH, NO3 and other organic functional groups on the parti...

Iron oxide (Fe3O4) nanoparticles have been used in many biomedical approaches. The toxicity of Fe3O4 nanoparticles on mammalian cells was published recently. Though, little is known about the viability of human cells after treatment with Fe3O4 nanoparticles. Herein, we examined the toxicity, production of reactive oxygen species, and invasive capacity after treatment of human dermal fibroblasts...

The need for high purity hydrogen for use in lowtemperature fuel cells has led to a resurgence of interest in the purification of hydrogen derived from reforming carbon -based feedstocks. A common process used to reduce the carbon monoxide concentration of the reformate gas to an acceptable level is the water gas shift reaction (WGSR). In the reaction, carbon monoxide is combined with water to ...
