Activated carbon/CuO (AC/CuO) composites were prepared through a facile one-step hydrothermal method and used as a bifunctional material for adsorption and catalysis degradation of bisphenol A (BPA). The composite was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and X-ray powder diffraction (XRD). The obtained AC/CuO exhibited excellent adsorption and catalytic performance. The maximum adsorption capacity of BPA on the AC/CuO was 319.03 mg/g according to the Langmuir fitting. At an initial BPA concentration of 20 mg/L, the BPA degradation efficiencies were maintained above 96% for 15 min by using 20 mg/L AC/CuO and 2 mM peroxymonosulfate (PMS). Moreover, the relationship between adsorption and catalytic degradation was also investigated. The results indicated that the pre-adsorption disfavored the degradation reaction. This work not only provides a novel preparation method for AC/CuO catalyst, but also gives a deeper insight into the mechanisms between adsorption and catalytic degradation.

活性炭/ CuO（AC / CuO）复合材料是通过一种简便的一步水热法制备的，并用作双功能材料，用于双酚A（BPA）的吸附和催化降解。通过傅立叶变换红外光谱（FT-IR），扫描电子显微镜（SEM）和X射线粉末衍射（XRD）对复合材料进行表征。所得的AC / CuO表现出优异的吸附和催化性能。根据Langmuir拟合，BPA在AC / CuO上的最大吸附容量为319.03 mg / g。在初始BPA浓度为20 mg / L时，通过使用20 mg / L AC / CuO和2 mM过氧一硫酸盐（PMS），可以将BPA降解效率保持在96％以上，持续15分钟。此外，还研究了吸附与催化降解之间的关系。结果表明，预吸附不利于降解反应。这项工作不仅为AC / CuO催化剂提供了一种新颖的制备方法，而且使人们对吸附和催化降解之间的机理有了更深入的了解。
