Chemical looping combustion (CLC) is a key technology for oxy-fuel combustion with inherent separation of CO2 from a flue gas, in which oxygen is derived from a solid oxygen carrier. Multi-cycle CLC performance and the product selectivity towards CO2 formation were achieved using mixed oxide of Cu and Mn (CuMn2O4) (Fd3[combining macron]m, a = b = c = 0.83 nm) as an oxygen carrier. CuMn2O4 was p...

cumn2o4 nanoparticles, a semiconducting materials with tunable functionalities in solid oxide fuel cell, was successfully synthesized via a sol-gel method using its respective metal cations sources i.e. cu2+ and mn2+ in an appropriate complexing agent.the vibrational frequencies below 1000 cm-1 of the obtained materials confirmed the formation of metal-oxygen (m-o:cu-o, mn-o) bond in the sample...

The work is the report about stearic acid sol-gel synthesis method, magnetically, electricalcharacterization and activation energy of copper manganese oxide nanostructures. The CuMn2O4 nanostructures are synthesized at a temperature of 600°C using the sol-gel method. The structural analysis using X-ray diffraction (XRD) and Scherrer equation show that the crystallite size of CuMn2O4 is ab...

Tetragonal distorted spinel of CuMn2−xTixO4 (x = 0, 0.25 and 0.50) was prepared by solid state reaction method followed neutron diffraction, FTIR spectroscopy, dielectric spectroscopy magnetic measurements. The confirmation regarding phase formation identification additional has been carried out analysing the room temperature diffraction. Besides, data have also assisted in ascertaining these r...

The oxidation of carbon monoxide was studied on oxide Cu–Mn–Fe catalytic systems with metal ratio Cu:Mn:Fe=1:1:1; 2:1:1; 1:2:1 and 1:1:2 obtained by the sol-gel method combustion. results X-ray phase analysis showed that have a complex composition. Along double oxides manganese iron, ferrites copper-, manganese, copper manganite, manganese-substituted were formed (CuFe2O4; Mn0.43Fe2.57O4, Mn0.9...

Introduction For emissions control of multicomponent exhaust gas streams, catalytic converters have to perform three functions: the catalytic oxidation of carbon monoxide to carbon dioxide, the destruction of Volatile Organic Carbon compounds (VOC’s), and NOx abatement. State-of-art catalysts for CO oxidation are based on CuMn2O4 (hopcalite), for VOC combustion on Pt/alumina, and for DeNOx eith...
