Effect of the solvent molar ratios on the synthesis of zeolitic imidazolate framework 8 (ZIF-8) and its performance in CO2 adsorption

In this research work, ZIF-8 was synthesized at room temperature using different synthesis solutions contained different molar ratios of methanol to zinc nitrate. The properties of the resultant particles were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM) and th...
