In this study, the elemental mercury removal behavior of metal (copper or nickel)/activated carbon hybrid materials were investigated. The pore structures and total pore volumes of the hybrid materials were analyzed using the N2/77 K adsorption isotherms. The microstructure and surface morphologies of the hybrid materials were characterized by X-ray diffraction and scanning electron microscopy, respectively. In the experimental results, the elemental mercury adsorption capacities of all copper/activated carbon hybrid materials were higher than that of the as-received material despite the decrease in specific surface areas and total pore volumes after the metal loading. All the samples containing the metal particles showed excellent elemental mercury adsorption. The Ni/ACs exhibited superior elemental mercury adsorption to those of Cu/ACs. This suggests that Ni/ACs have better elemental mercury adsorption due to the higher activity of nickel.
在本研究中，对金属（铜或镍）/活性炭混合材料的元素汞去除行为进行了研究。使用N2/77 K吸附等温线分析了混合材料的孔结构和总孔体积。分别通过X射线衍射和扫描电子显微镜对混合材料的微观结构和表面形貌进行了表征。实验结果表明，尽管金属负载后比表面积和总孔体积有所下降，但所有铜/活性炭混合材料的元素汞吸附容量均高于原样材料。所有含有金属颗粒的样品都表现出优异的元素汞吸附性能。镍/活性炭对元素汞的吸附性能优于铜/活性炭。这表明由于镍的活性较高，镍/活性炭具有更好的元素汞吸附性能。
