چکیده مقاله:
Nanocrystalline CuCr2O4 spinel catalysts were synthesized by surfactant-assisted hydrothermal method and the effect of calcination temperature was investigated on the textural properties of the catalysts. The catalytic performance of the prepared catalysts was studied in CO oxidation reaction. The powder X-ray diffraction (XRD), N2 adsorption-desorption (BET) and pore size distribution (BJH) techniques were used for characterization of the prepared samples. The results showed that changes in the calcination temperature has a significant impact on the crystalline phases and the catalytic activity. The catalyst calcined at 500 °C has the best performance due to its high crystallinity and surface area compared to other catalyst. The catalyst also showed high stability without any decline in CO conversion.
