Аннотация

A direct synthesis of pillared metal-organic frameworks with Kagomé net topology under mild conditions (room temperature and ambient pressure) was developed which provides a straightforward and energy-saving procedure to produce MOFs. A series of metals (M = Zn, Ni and Co) bridging with ligands 1,4-benzene dicarboxylate (bdc) and 1,4-diazabicyclo[2.2.2]octane (dabco) were used to construct MOF frameworks denoted as M2(bdc)2(dabco). The Kagomé net pillared structures were confirmed via crystal phase analysis (XRD). The use of different metals resulted in diverse crystal morphologies and particle shapes as observed from scanning electron microscope analysis (SEM). The obtained Kagomé net pillared structure influences the physical properties such as surface area, pore size, N2/CO2/CH4 gas adsorption and also thermal stability. Furthermore, modeling was applied to determine the behavior of the isosteric heat of adsorption on CO2 and gas selectivity of CO2/CH4 and CO2/N2.
