Abstract

This work explores the capacity of metal-organic framework (MOF)-polyvinyl alcohol (PVA) composites (MOF@PVA beads) in volatile organic compound (VOC) adsorption. The selected MOFs include HKUST-1, MIL-68, ZIF-8, A520, ZIF-67, and CAU-10, wherein the MOFs were optimized to be synthesized on a larger scale of production. Various proportions of the MOF@PVA bead composites were prepared to evaluate the optimal ratio to yield the best adsorption capacity. Most of the prepared MOF@PVA beads exhibited a higher VOC adsorption capacity as compared to commercially available activated carbon and zeolite adsorbents, proving the universality of the method of preparation. Among the composites, the MIL-68@PVA beads exhibited the best static VOC adsorption, while HKUST-1@PVA beads exhibited the best dynamic low concentration (200 ppm) toluene adsorption capacity.
