Effects of Co Ion Dispersion upon Selective Catalytic Reduction of NO on CoO/Al_2O_3 Catalysts
In alumina-supported cobalt oxide catalyst prepared by sol-gel method, cobalt ions were highly dispersed so as to react with alumina at 773 K to form cobalt aluminate, which enhanced the activity for SCR-NO reaction by propene. While in the catalyst by impregnation cobalt aluminate was not formed at 773 K, which resulted in the poor activity for SCR-NO reaction.
