High selective 2DCOFs for Resources Recovery from Electronic-Waste

Recovery of precious and critical metals (Au, Nd) from e-waste not only has substantial economic and environmental advantages but also addresses the problem of resource scarcity. In this area, the adsorption approach is recognized as an efficient, facile, and green methodology. Recently, covalent organic frameworks (COFs) have emerged as potential adsorbents for metal recycling from waste materials. However, there are still key challenges that need to be addressed: (1) poor selectivity against interferents
