摘要：

This, study reports ZIF-8 and its g-C3N4 based composites for successful adsorption of carbon dioxide gas at temperature of 45 & DEG;C and 0-15 bar pressure. These samples were characterized via using different techniques like XRD, EDX, SEM, FTIR to study the structural and morphological properties, The SEM results shows rougher and porous rhombic dodecahedron morphology, and the EDX analysis confirms that the catalyst production is free of impurities. The FTIR and XRD analyses show all the peaks and bands correspond to crystalline structure and necessary functional group presence in the prepared adsorbents. The ZIF-8 and its g-C3N4 composites have good adsorption capacity. Among them ZIF-8@3wt% g-C3N4 shows the highest adsorption capacity of 315 mg g(-1) at 45 & DEG;C and 0-15 bar pressure. The rising adsorption trend of all prepared materials shows that these samples do not reach their saturation point and can still adsorb more CO2 even at a pressure higher than 15 bar. [GRAPHICS]
