Abstract

This study focuses on pre-synthetic functionalized MOF material normally known as pillared layer MOFs. An additional component DABCO (1,4-diazabicyclo[2.2.2] octane) is added to the MOFs which works as a pillar to produce 3d structured MOFs. Zn-BDC-DABCO and Co-BDC-DABCO were studied for their performance in CO2 capture application. The addition of DABCO turns the 2d-layered metal-BDC lattice to a 3d structure with enhance performance for CO2 capture. The MOFs were characterized using XRD, SEM, TGA, FTIR and BET and the CO2 capture capacity was tested at 25°C and 0-25 bar. Zn-BDC-DABCO and Co-BDC-DABCO showed a maximum adsorption capacity of 6.3 and 4.4 mol/kg CO2.
