Abstract

Liquid phase adsorption of benzothiophene (BT) has been studied over CuCl₂-loaded analogous metal-organic frameworks (MOFs), metal-benzenedicarboxylates (Me-BDCs, Me: Al, Cr and V), to understand the effect of central metal ions on the adsorptive removal of BT from a model fuel. Among the central metal ions (Al³⁺, Cr³⁺ and V³⁺) of the Me-BDCs only V³⁺ was oxidized by the loaded CuCl₂ (or Cu²⁺) at ambient condition resulting in V⁴⁺ and Cu⁺ species. Different from the CuCl₂-loaded Al- and Cr-BDCs, the CuCl₂/V-BDC adsorbed BT remarkably well compared to the virgin V-BDCs which suggests a specifi{ligature}c favorable interaction (π-complexation) between the obtained Cu⁺ in the CuCl₂/V-BDC and BT.
