Abstract:Bi added to Co3O4 by coprecipitation method significantly decreased the average crystalline size of Co3O4 and increased the surface area and the active sites of the catalyst in population for catalyzing the N2O decomposition. Over Bi0.02Co that was the optimized from the BixCo catalysts, 2000 ppm of N2O in pure Ar was completely decomposed at 400 degrees C in GHSV of 20,000 h(-1). Outstandingly, the catalyst exhibited a strong resistance to CO2, stable CO2 conversion larger than 95% was obtained over the catalyst in the presence of 10% CO2 at the reaction temperature.
