摘要：
In this work, we present the preparation of MOF-5 using terephthalic acid as a ligand obtained from polyethylene terephthalate waste. The results showed that the obtained terephthalic acid gave similar features to the commercial one. The synthesized MOF was fully characterized and tested for CO2 adsorption at 35 degrees C and at atmospheric pressure, under static and dynamic conditions, presenting adsorption capacities of 2.5 and 2 mmol g(-1), respectively, which are higher than the reported values. At 1000 kPa, in static conditions, the adsorption capacity was 7.8 mmol g(-1). The obtained results demonstrated that this MOF presented improved structural stability and CO2 adsorption capacity compared with the results reported elsewhere.
