Nanostructured copper (Cu)/nickel- (Ni-) coated nanoporous carbon sheets (NCS) were prepared to improve the toxic acidic vapor (hydrogen chloride, HCl) removal efficiency of NCS using a continuous bimetal electroplating method at various metal content ratios. The surface morphology and nanostructure of Cu/Ni-NCS were observed by scanning electron microscopy and X-ray diffraction, respectively. N2/77 K adsorption isotherms were investigated using the Brunauer-Emmett-Teller equation. HCl vapor removal efficiency was confirmed using two types of detection techniques: a gas detecting tube for low concentrations and gas chromatography for high concentrations. HCl removal efficiency was improved mainly in the copresence of nanostructured Cu/Ni clusters compared to the efficiencies of the as-received and single-metal-plated NCS. In particular, the removal efficiency of Cu/Ni-3 was increased by 270% compared to that of as-received sample, but Cu/Ni-5 showed lower efficiency than Cu/Ni-3, indicating that suitable metal composition on NCS can accelerate HCl removal behaviors of the NCS.
