Copper-containing porous carbon derived from MOF-199 for dibenzothiophene adsorption†
Abstract
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.
