英文摘要density functional theory has been employed to investigate the pi-complexation adsorption of aromatic sulfur compounds such as thiophene (tp), benzothiophene (bt), dibenzothiophene (dbt), and 4, 6-dimethyldibenzothiophene (4, 6-dmdbt) by ion exchanging faujasite type zeolites with cu+ and ag+ cations. the calculations were based on the cluster models of 16t (h22si15alo22), and performed with blyp function and dnp basis set. the effective core potential basis set was used for transition metal atoms. the calculated interaction energies indicated that the adsorption ability of the ion exchanging y zeolites for thiophenic compounds followed the order: cu(i)-y > ag(i)-y. their adsorption ability for thiophenic compounds is higher than that for benzene. the calculated adsorption energy of the thiophenic compounds increased as 4, 6-dmdbt < dbt < tp < bt, which agrees with the experiment. the natural bond orbital (nbo) analysis of the second-order perturbative energy have been performed to investigate the pi-complexation adsorption mechanism of thiophene and benzene on cu(i)-y and ag(i)-y sorbents.
