  Abstract

Researchers around the world are looking for ways to improve or develop new technologies to mitigate the emissions of CO2 present in greenhouse gases. Amines are currently the most used substances to capture CO2. The ionic liquids (ILs), however, have also been considered promising materials. Recently, mixtures of ILs and amines have been studied for this purpose. The ILs are also being supported in solid matrices (polymers, zeolites, cellulose, and membranes) to obtain stable, easy to handle, and reusable materials. Cellulose fibers make a promising matrix, considering their affinity with CO2, renewable feature, and thermal, mechanical, and chemical stability. To improve the CO2 capture capacity by using cellulose and the mixture of ILs and amines, we prepared mixtures of the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM][BF4] and monoethanolamine or triethanolamine. Then, we dropped the mixtures on natural cellulose fibers from pineapple leaves. This paper reports the characterization of the composite materials by FTIR, XRD, XPS, FESEM, and TGA-FTIR in order to evaluate their structure, composition, morphology, and thermal behavior. We also report the CO2 sorption capacity at 25
