Synthesis of a nano porous cobalt based MOF, [Co6(oba)6(CH3O)4(O)2]n·3DMF has been carried out to introduce a new and highly efficient adsorbent of dibenzothiophene (DBT). This compound has been synthesized by sonochemical method using a nonlinear dicarboxylate ligand. Adsorption capacity of this MOF has been investigated in presence of dibenzothiophene (DBT) as a refractory poly-aromatic sulfur compound. We choose this MOF with oba oxygen donor ligand (H2oba = 4,4ʹ-oxybisbenzoic acid) and one unsaturated coordination number around Co metal as the active site with the maximum adsorption value of DBT at around 825 mg/g. An increase at about 2 times in the maximum adsorption value of DBT was observed in presence of this MOF nanostructure as an effective adsorbent.
