【摘要】：以Cu(NO_3)_2溶液作为前躯体,采用浸渍煅烧法对盐酸预处理后的活性炭纤维(activated carbon fiber,ACF)毡进行负载氧化铜化学改性,制备CuO/ACF电极材料。通过扫描电镜(SEM)、X射线光电子能谱仪(XPS)、比表面积及孔径分析仪以及傅立叶变换红外光谱仪(FTIR)对ACF及其负载CuO后的形貌与结构、元素组成、比表面积、孔径等进行观察与分析,并利用电化学工作站测试其电化学性能。结果表明:经过负载CuO化学改性的CuO/ACF电极材料,比表面积及孔容较改性前分别下降31.94%和33.95%,表面含氧基团增多,出现明显的Cu—O键,CuO/ACF电极材料中Cu元素的质量分数为13.7%;负载CuO后比电容升高17.95%,电吸附性能提高。CuO/ACF材料可作为电极材料用于去除废水中的无机盐离子。
[Abstract]:Cu(NO_3)_2 solution was used as precursor to prepare CuO/ACF electrode material by chemical modification of activated carbon fiber activated carbon fiberine (Cu(NO_3)_2) felt pretreated with hydrochloric acid. The morphology, structure, element composition, specific surface area and pore size of ACF and its loaded CuO were observed and analyzed by scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), specific surface area and aperture analyzer and Fourier transform infrared spectroscopy (FTIR). The electrochemical performance was tested by electrochemical workstation. The results showed that the specific surface area and pore volume of the modified CuO/ACF electrode materials modified by CuO decreased 31.94% and 33.95%, respectively, and the oxygen groups on the surface increased. The mass fraction of Cu in CuO / ACF electrode material is 13.7, the specific capacitance increases 17.95% after loading CuO, and the electrical adsorbability is improved. CuO / ACF material can be used as electrode material to remove inorganic salt ions in wastewater.
