High-performance CrxFe2-xO3 mixed oxides for catalytic combustion of dichloromethane

A Study of Catalytic Performance of Co3O4 and Cu-Co Nano Metal Oxides in Combustion of Aromatics

Two Cu-Co and Co3O4 oxides were synthesized by the conventional sol-gel auto-combustion and their physical-chemical properties were characterized by XRD, FTIR, SEM, TPR and XPS. The XRD results indicated that copper-cobalt oxide appeared in a mixture form of Cu0.15Co2.85O4 spinel and CuO phases, whereas the cobalt oxide exhibited in the pure form of Co3O4 spinel. The FTIR approved the formation...

Copper-manganese mixed oxides: CO2-selectivity, stable, and cyclic performance for chemical looping combustion of methane.

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...

Preparation, Structure and Selected Catalytic Properties of La2CuO4 Nano Mixed Metal Oxides

The perovskite-structured La2CuO4 nanoparticles have been synthesized via an ultrasonic-assisted co-precipitation route using octanoic acid as organic surfactant, and the phase composition, morphology, lattice parameters and size of nanoparticles are characterized through Fourier transform infrared spectrosco...

Development of Synergic Mixed Metal Oxides for the Combined Catalytic-Absorptive Removal of Nitric Oxide from Diesel Exhaust

The NO removal over oxide sorbents (K2O/Al2O3 , CaO/Al2O3 and BaO/Al2O3) at a loading of up to 25 wt.% was investigated using a synthetic diesel exhaust gas containing  1,000 ppm NO, 1000 ppm iso-butane (i-C4H10), 8% O2 and N2 balance. The reactor was operated  at 250 <su...
