以糠醇为碳前驱体填充MOF-199硬模板孔，经炭化和活化，首次合成了一种新型含铜多孔炭。通过XRD、SEM、TEM、ICP、XPS和N2吸附等测试手段对所制备的炭材料的织构特性进行了表征。通过静态吸附实验考察了二苯并噻吩在3种模拟油中的吸附性能。平衡数据由Langmuir等温模型最好地表示，显示最大单层吸附容量为59 μg g−1，远高于文献中报道的一些其他吸附剂。综合上述优点，含铜多孔炭在实际深度脱硫，特别是噻吩类化合物的脱除方面具有很好的应用前景。
A novel type of copper-containing porous carbon has been synthesized by filling the pores of MOF-199 hard template with furfuryl alcohol as carbon precursor, followed by carbonization and activation for the first time. The textural properties of the as-prepared carbon material were proven by examinations with XRD, SEM, TEM, ICP, XPS and N2 adsorption. The adsorption performance of dibenzothiophene in three types of model oils was investigated by batch tests. The equilibrium data was best represented by the Langmuir isotherm model, showing a maximum monolayer adsorption capacity of 59 μg g−1, which was much higher than some other adsorbents reported in the literature. Considering all the advantages, the as-prepared copper-containing porous carbon shows promising potential for practical deep desulfurization, especially for thiophenic compound removal.
