Low-temperature SCR of NO with NH3 over CeO2 supported on modified activated carbon fibers

►ACF was treated by nitric acid and low-temperature oxygen plasma respectively. ►Characterized the catalyst by SEM, BET and XRD methods. ►The optimum catalytic activity was observed at 180 °C with a loading of 9 wt.% CeO2. ►CeO2/ACFN showed higher catalytic activity than CeO2/ACFP in the same situation.
