Abstract
Ag particles were precipitated on an activated carbon fiber (ACF) surface using a liquid phase plasma (LPP) method to prepare a Ag/ACF composite. The efficiency was examined by applying it as an adsorbent in the acetaldehyde adsorption experiment. Field-emission scanning electron microscopy and energy-dispersive X-ray spectrometry confirmed that Ag particles were distributed uniformly on an ACF surface. X-ray diffraction and X-ray photoelectron spectroscopy confirmed that metallic silver (Ag0) and silver oxide (Ag2O) precipitated simultaneously on the ACF surface. Although the precipitated Ag particles blocked the pores of the ACF, the specific surface area of the Ag/ACF composite material decreased, but the adsorption capacity of acetaldehyde was improved. The AA adsorption of ACF and Ag/ACF composites performed in this study was suitable for the Dose–Response model.

Summary
Volatile organic compounds (VOC) is a generic term for liquid or gaseous organic compounds that can evaporate into the atmosphere because of their low boiling point. Adsorption, photocatalytic oxidation, plasma oxidation, and the like are known as treatment methods for the removal of acetaldehyde Since it has problems such as limited decomposition reaction, generation of by-products (photocatalytic oxidation), and generation of nitrogen dioxide and ozone (plasma oxidation), an adsorption method using an absorbent is generally used the most [6]. Carbon materials such as activated carbon (AC) have many advantages, such as high surface area, thermal stability, inexpensiveness, and renewability, and are used as major adsorbents [5,7]. The acetaldehyde adsorption experiment was performed using Ag/ACF composite as an adsorbent, and the pure ACF and adsorption performance were compared and evaluated
