Abstract:
In this study, activated carbon fibers (ACFs) were treated by a Ni-electroplating technique in order to remove nitric oxide (NO). The surface properties of the ACFs were investigated by XPS measurement. N2/77 K adsorption isotherm characteristics were determined by the BET equation. Also, NO-removal efficiency was confirmed by gas chromatography. For experimental results, Ni2p was introduced on ACFs during the Ni-electroplating technique. The nickel deposited on ACFs appeared to increase the NO removal despite the decrease in the BET specific surface areas and micropore volumes compared to nontreated ACFs. Consequently, it was found that NO conversion of ACFs was significantly improved due to the catalytic reaction of nickel deposited on ACFs.
