Abstract

The present study concerns chromium benzenedicarboxylates MIL-53 and MIL-101 hydrothermal syntheses utilizing acetic acid, and their capabilities for CO2 adsorption. The effect of the parameters such as reaction time, reaction temperature, water concentration, and acetic acid content on adsorption characteristics of these metal-organic frameworks (MOFs) is investigated using L8 Taguchi experimental design. In synthesized MIL-101, with adding 1 acetic acid equivalent with respect to Cr, reaction time and temperature have been reduced from 24 h and 483 K to 6 h and 463 K. Also, the CO2 adsorption capacity has been measured by a volumetric method. The results have revealed that adding acetic acid and reducing water in the reaction mixture results in converting MIL-101 to MIL-53 which tends to an increase in CO2 adsorption. With regard to reaction conditions, the results show that MIL-53 and MIL-101 have the maximum CO2 adsorption capacities of 17.5 and 11.0 mmolg-1 at 3.5 bar and 299.2 K, respectively.
