Efficient adsorbents for industrial wastewater treatment are important to minimize potential environmental damage. In particular, organic dyes, as a significant group of industrial pollutants, are usually highly water soluble, non-degradable and many are toxic to carcinogenic. Changxia Li and Freddy Kleitz from the Faculty of Chemistry of the University of Vienna together with colleagues now presented a new approach to design an innovative composite material, consisting of a nanoporous, ultrathin covalent organic framework (COF) anchored on graphene, that is highly efficient at filtering organic pollutants from water. The study was published in Angewandte Chemie.
