Removal of Heteroaromatic Sulfur Compounds by a Non-noble Metal Fe Single-atom Adsorbent
文献摘要：
Sulfur-containing compounds (SCCs) must be removed from fuels before use. In this study, a novel non-noble metal Fe single-atom adsorbent (SA-Fe/CN) was synthesized using a core–shell strategy and applied for the adsorptive removal of benzothiophene (BT) and dibenzothiophene (DBT). The adsorption isotherms, thermodynamics, kinetics, and adsorption–regeneration cycles of DBT and BT on SA-Fe/CN were studied. SA-Fe/CN exhibited a significant capacity to adsorb DBT, and the isothermal equilibrium was well described by the Langmuir isotherm. The Gibbs free energy values were negative (ΔG0 <0), indicating that the adsorption of DBT and BT was favored and spontaneous. The adsorption process conformed to the pseudo-second-order kinetic model with high R2 values (0.9994, 0.9987). The adsorption capacity of SA-Fe/CN for DBT and BT reached 163.21 mg/g and 90.35 mg/g, respectively, due to the highly active sites of the single atom and electrostatic interaction with the sulfide. Therefore, SA-Fe/CN may be a promising adsorbent for SCC removal.
