Activity of Cu-Co-M (M= Ce, Ni, Au, Mg) catalysts prepared by coprecipitation method, calcined at high temperature for CO oxidation
The present study deals with analysis of the activity of catalysts prepared by addition of different metals to Copper and Cobalt based catalysts for CO oxidation and the variation in activity caused by changes in composition. A series of catalysts were prepared with Cu:Co molar ratio 1:4 and a third metal (M= Ce, Ni, Au, Mg) was added in three different quantities. Compositions were prepared by...

متن کاملMagnetic Properties and Structural Study of Ni-Co/Cu Multilayers Prepared by Electrodeposition Method
Ni-Co/Cu multilayers have been grown by electrodeposition method from a single electrolyte (based on Ni(SO4).6H2O, Co(SO4).7H2O, Cu(SO4) and H3BO3) using galvanostatic control on titanium sublayers. The X-ray diffraction (XRD) patterns confirmed the multilayered structure with the nanometer thicknesses. Also, electron diffraction x-ray (EDX) analysis confirmed the purity of deposited samples. ...
متن کاملMagnetic and structural properties of M-type barium hexaferrite prepared by co-precipitation
Stoichiometric and single-phase barium hexaferrite (BaM) has been synthesized by co-precipitation and an additional solid state preparative method using high-purity nitrates, oxides and carbonates of iron (III), barium (II) and ammonium hydroxide. The isochronally and isothermally measured permeability and magnetic loss tangents over 1MHz–1GHz in frequency remained moderately constant until a s...
متن کاملSynthesis and magnetic investigation of cobalt ferrite nanoparticles prepared via a simple chemical precipitation method
In this research cobalt ferrite (CoFe2O4) nano-crystalline powders were prepared by simple chemical precipitation method using cobalt sulfate. The CoFe2O4 nanoparticles were characterized by X-ray diffraction, scanning electron microscopy and Fourier transform infra-red spectroscopy. The crystallite size of CoFe2O4 nanoparticles was calculated by Debye–Scherrer formula. The effect of precursor...
