Microwave-assisted Synthesis of CuCl-MIL-47and Application to Adsorptive Denitrogenation of Model Fuel: Response Surface Methodology

摘要

Today,energy-environment concerns are crucial for humans.Environmental pollution will increase as a result of expanding the use of fossil fuels,nitrogen-containing compounds(NCCs)of which cause destructive effects on the environment.In this study,adsorptive denitrogenation(ADN)was performed by adsorbing indole(IND)from model fuels and gasoline over Metal-organic frameworks(MOFs)CuCl-MIL-47.The MIL-47 was synthesized by the microwave method with modified CuCl.In the present study,the application of Central Composite Design(CCD)was evaluated in the ADN process optimization for the first time.The maximum adsorption capacity(Q0)CuCl-MIL-47 for indole(IND)was 769.2 mg/g.Herein,π-complexation of IND with Cu has made a synergistic effect leading to an increase in Q0.Moreover,the reusability of CuCl-MIL-47 was confirmed through its regeneration via ethanol.
