The appeal of metal–organic frameworks (MOFs) in wastewater treatment is tempered by their polycrystalline, powdery state, and challenges associated with deployment. In the case UiO-66, one most stable widely-used MOFs, a low tendency for removing some organic contaminants has been observed on top mentioned issues. To address these challenges, herein, we take two complementary steps, i.e., hybridization UiO-66 nanodiamond (ND) followed integration hybrid nanoparticles electrospun polymeric nanofibers based chitosan/polyvinyl alcohol (PVA). We present electrospinning polymer/MOFs as promising technique to fabricate highly efficient adsorbents water remediation. use chitosan/PVA (ECPN) versatile host MOF that remove cationic methylene blue anionic Congo red dyes.
