The rapid escalation of atmospheric carbon dioxide (CO2) concentrations has raised an alarming surge in global temperatures, consequently contributing to global warming. This phenomenon is irreversible and has detrimental consequences for our planet. Unfortunately, current technologies and methodologies have proven inadequate in mitigating atmospheric CO2 levels to the good indoor air quality. Hence, the pressing need to conceive and develop innovative and cost-effective CO2 removal techniques and technologies. Metal-organic frameworks (MOFs) have emerged as promising materials in the pursuit of effective CO2 removal, owing to their distinctive properties. Characterized by their porous structures and expansive internal surface areas, MOFs exhibit a remarkable capacity for CO2 adsorption. In this study, we embarked on the synthesis of MOFs employing aluminum chloride hexahydrate in conjunction with two distinct organic ligands, namely, benzene-1,3,5-tricarboxylic acid (BTC) and benzene-1,4-dicarboxylic acid (BDC). Our research endeavors aimed to study the influence of varying molar ratios of metal precursor to organic ligand on the adsorption capacity and structural characteristics of the resultant MOF structures. The results elucidated that Al-BDC possesses superior CO2 adsorption performance relative to Al-BTC. Specifically, the 1:3 molar ratio of Al-BDC emerged as the highest CO2 adsorption performance among all the assessed samples. This finding suggested the potential suitability of Al-BDC for CO2 adsorption applications.
