STUDY OF LOW-TEMPERATURE OXIDATION OF CARBON MONOOXIDE ON Cu–Mn–Fe CATALYTIC OXIDE SYSTEMS OBTAINED BY THE SOL-GEL COMBUSTION METHOD
نویسندگان
چکیده
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, Mn0.98Fe2.02O4; CuMn2O4; Cu1.2Mn1.8O4; Cu0.5Mn0.5Fe2O4). It has been found depending metals in catalyst, reaction start temperature is range 120–1700C. And after 3–5 minutes reaction, conversion begins to increase sharply, reaching 100% within next 5

STUDY OF THE OPTIMUM CALCINATION TEMPERATURE FOR THE SYNTHESIS OF STRONTIUM HEXAFERRITE MAGNETIC CERAMIC NANOPOWDER BY A SOL-GEL AUTO-COMBUSTION METHOD IN THE PRESENCE OF CATIONIC SURFACTANT
In this research the sol-gel auto-combustion method was used to prepare strontium hexaferrite nanopowder. A solution of distilled water, ferric and strontium nitrates, citric acid, trimethylamine, and n-decyltrimethylammonium bromide cationic surfactant, was heated to form a viscous gel. The gel was heated and then ignited automatically. As-burnt powder was calcined at temperatures from 700 to ...

Catalytic Oxidation of Carbon Monoxide by Cobalt Oxide Catalysts Supported on Oxidized-MWCNT
Cobalt oxide catalysts supported on oxidized multi-walled carbon nanotubes (MWCNT) for the low-temperature catalytic oxidation of carbon monoxide were prepared by an impregnation-ultrasound method. These catalysts were characterized by N2 adsorption/desorption, TEM, XRD, Raman, and H2-TPR methods. The XRD and Raman results indicated that the phase of the synthesized cobalt...
