In this study, the activated carbon fibers(ACFs) coated with copper metal were prepared by electroplating technique to remove nitric oxide(NO). The surface properties of ACFs were determined by pH measurement. And microstructures of ACFs were investigated by XRD analysis. The surface morphology was observed with a SEM. The specific surface area and micropore volume were determined by $N_2$/77K adsorption isotherms and t-plot methods, respectively. And, NO removal efficiency was measured by gas chromatographic technique. From the experimental results, the copper metal supported on ACFs appeared to increase NO removal with the sacrifice of the BET specific surface area, micropore volume, and microporosity of the ACFs. The Cu content in ACFs and reaction temperature played an important role in improving the NO removal, which was probably due to the catalytic reactions of C-NO-Cu.
