Abstract EN
This paper investigates the effects of CuO contents in the CuO-CeO2 catalysts to the variation in physical properties of CuO/CeO2 catalysts and correlates them to their catalytic activities on selective CO oxidation.
The characteristic of crystallites were revealed by X-ray diffraction, and their morphological developments were examined with TEM, SEM, and BET methods.
Catalytic performance of catalysts was investigated in the temperature range of 90–240°C.
The results showed that the catalyst was optimized at CuO loading of 20 wt.%.
This was due to the high dispersion of CuO, high specific surface area, small crystallite sizes, and low degree of CuO agglomeration.
Complete CO conversion with near 100% selectivity was achieved at a temperature below 120°C.
The optimal performance was seen as a balance between CuO content and dispersion observed with growth, morphology, and agglomeration of nanostructures.
