The synthesis procedure of ZIF-8 involves the addition of chemical reagents at room temperature. ZIF-8 was characterized using XRD (Figure ), nitrogen adsorption-desorption isotherm (Figure ), TGA (Figure ). XRD patterns of ZIF-8 and simulated patterns are matched to each other, indicating the synthesis of the pure phase of ZIF-8 (Figure ). Nitrogen adsorption-desorption isotherm shows IV type with hysteric's type indicating the presence of micropore-mesopore structure (Figure ). The pore size distribution was evaluated using HK (Figure ) and DFT (Figure ) methods for micropore and mesopore regimes, respectively.
