DEVELOPMENT OF MIL 53(Al)-BASED COMPOSITES FOR CARBON CAPTURE IN BUILDING ENVELOPES

Abstract
This study investigates the development of composite materials combining traditional construction substances like cement, gypsum, or recycled ceramic sourced from building demolition waste with MIL-53(Al) a microporous Metal Organic Framework. These composites, aimed for building envelopes, bound with Polyvinyl Alcohol, MethylCellulose, Ethanol, and water, show promise for carbon dioxide (CO2) adsorption in buildings. The composites, comprising 6-8% MIL-53 (Al), 50-60% construction materials, and 30-40% binders, demonstrate effective CO2 capture at standard conditions. According to the results, the composites, based on the combination of their components, offer a range of adsorption capacities, from 1.72 cm³/g to 9.42 cm³/g at 273 K and from 0.94 cm³/g to 4.79 cm³/g at 298 K. Thermal analysis confirms their stability up to 200°C, and X-ray diffraction shows that MIL-53 (Al) maintains its structure, ensuring the adsorption properties of the final composites. Moreover, the manufacturing process of these composites allows for mass production utilizing additive 3D printing techniques.
