Hierarchically structural PAN/UiO-66-(COOH)2 nanofibrous membranes for effective recovery of Terbium(III) and Europium(III) ions and their photoluminescence performances

Metal organic frameworks (MOFs) as adsorbents are attracting wide attention due to their high porosity and rich functionalities. However, their intrinsic fragility and poor separability limited their practical applications. Herein, an intriguing MOF UiO-66-(COOH)2 nanoparticles with abundant carboxyl functional groups were embedded in polyacrylonitrile (PAN) nanofibers by colloid-electrospinning technique to construct flexible MOF nanofibrous...
