“…Therefore, it is essential to detect UO 2 2+ for eco-environmental protection and, further, adsorb it for uranium recovery. 4,5 In recent years, many new nanomaterials such as metal− organic frameworks, photonic crystals, porous polymers, quantum dots, carbon dots, and metal nanoparticles have been applied for UO 2 2+ sensing; these materials offer unique traits such as operational simplicity and high sensitivity as well as enable on-site detection. 6−11 However, most of these materials can only quantitatively detect UO 2 2+ , while research on multifunctional materials capable of simultaneous detection and adsorption of UO 2 2+ , our strategic interest, is still in the preliminary stage.…”
