A microporous, amino acid functionalized Zn(ii)-organic framework nanoflower for selective CO2 capture and solvent encapsulation
A new homochiral metal organic framework, {[Zn-4(mu(3)-OH)(2)(d-2,4-cbs)(2)(H2O)(4)].5H(2)O}(n) (Zn-CBS), has been solvothermally synthesized using a new chiral amino acid based tricarboxylic acid ligand, (2-((4-carboxybenzyl)amino)succinic acid), H-3(d-2,4-cbs). Zn-CBS was characterized by various techniques like Fourier transform infrared spectroscopy (FTIR), UV-Vis solid-state diffuse reflectance spectroscopy, elemental microanalysis, thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD), field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), and energy dispersive X-ray analysis (EDX) and elemental mapping. The nanoflower arrangement in Zn-CBS is clearly seen from the FESEM and TEM images. Its microporous nature is established by the nitrogen adsorption measurements which exhibit a reversible type I isotherm with a BET surface area of 282 m(2) g(-1). Similarly, it shows a reversible type I isotherm for H-2 with an uptake of 0.5 wt% at 77 K. Based on its CO2 sorption isotherm with an uptake of 85.9 cm(3) g(-1) at 195 K, a high isosteric heat of adsorption (Q(st)) of 35 kJ mol(-1) at zero coverage is obtained. This is illustrated by its high potential of selectivity towards CO2 over N-2 and CH4 under ambient conditions (298 K and 1 bar). With the help of configurational bias Monte Carlo molecular simulation, this selectivity is explained for an effective interaction between CO2 and basic amine sites of the framework. The porous nature and functionality of Zn-CBS have also been utilized in encapsulating various small molecules, which is followed by FTIR, TGA and PXRD.
