Reducción catalítica selectiva de NOx usando nanopartículas de ferritas Cu1-XCoXFe2O4 como catalizador
Nanostructured catalysts AB2O4 spinel type oxides (A = Co and B = Cu) were prepared by the sol-gel self-combustion method using citric acid as precursor. They were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Catalytic activ...

| Summary: | Nanostructured catalysts AB2O4 spinel type oxides (A = Co and B = Cu) were prepared by the sol-gel self-combustion method using citric acid as precursor. They were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Catalytic activity tests, which have proven to be effective for selective catalytic reduction of NOx using hydrocarbon as a reducing agent (SCR-HC) in a temperature range 250 - 450 ° C, reaching up to 40% conversion of NO and 100% selectivity towards the formation of N2 |
