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 (Ag) and silver oxide (AgO) 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.

摘要

采用液相等离子体（LPP）法将银颗粒沉淀在活性炭纤维（ACF）表面，制备了Ag/ACF复合材料。通过将其作为吸附剂应用于乙醛吸附实验中来考察其效率。场发射扫描电子显微镜和能量色散X射线光谱证实银颗粒均匀分布在ACF表面。X射线衍射和X射线光电子能谱证实金属银（Ag）和氧化银（AgO）同时沉淀在ACF表面。虽然沉淀的银颗粒堵塞了ACF的孔隙，Ag/ACF复合材料的比表面积减小，但乙醛的吸附容量得到了提高。本研究中ACF和Ag/ACF复合材料对乙醛的吸附符合剂量反应模型。
