Catalytic activity of Co, Cu and Mn oxide catalysts synthesized by the sol-gel combustion method in the low-temperature oxidation of carbon oxide

The synthesis of catalysts based on cobalt, copper and manganese oxides by sol-gel method with combustion was carried out, their catalytic activity studied in the reaction low-temperature oxidation carbon monoxide to dioxide. Oxides manganese, as well double (Co–Mn, Cu–Mn Co–Cu) were synthesized. X-ray phase analysis showed formation manganites corresponding metals Co–Mn systems. It revealed that Co–Cu system only separate are formed. found cobaltmanganese copper-manganese oxide systems synthesized exhibit high (110–140 0C) conversion into One-step Cu–Mn/Al2O3 also out burning precursors binder hydrogel (Al2O3), its revealed. investigated diffraction, IR spectral methods, BET, SEM. results obtained show possibility obtaining active multicomponent technologically simple method.
