Activated carbon fibers (ACFs) were treated by electroless plating of CuO to improve their removal performance for volatile organic compounds (VOCs). The properties of these samples(CuO@ACFs) were evaluated by X-ray photoelectron spectroscopy (XPS), BET and N₂O chemisorption to determine the area and dispersion of metallic CuO. The removal efficiency for benzene was investigated by gas chromatography (GC). The breakthrough time of CuO@ACFs increased by approximately 120% compared to that of untreated ACFs at benzene of 100 ppm. CuO@ACFs removed 100% of the benzene in 20 h, indicating this material can be used as a removal technology for VOCs.

活性碳纤维（ACF）通过化学镀CuO进行处理，以提高其对挥发性有机化合物（VOC）的去除性能。通过X射线光电子能谱（XPS），BET和N ₂ O化学吸附作用对这些样品（CuO @ ACFs）的性能进行了评估，以确定金属CuO的面积和分散度。通过气相色谱法（GC）研究了苯的去除效率。与未处理的ACF在100 ppm的苯中相比，CuO @ ACFs的穿透时间增加了约120％。CuO @ ACFs在20小时内去除了100％的苯，这表明该材料可用作挥发性有机化合物的去除技术。
