Highlights
• A novel and facile approach for preparing metal-phenolic network (MPN) microspheres was demonstrated.
• The prepared MPN microspheres exhibited a high adsorption capacity for various pollutants.
• The adsorbed pollutants could be easily desorbed using an ethanol/water solution.
Abstract
Metal-phenolic networks (MPNs) are a versatile class of self-assembled systems that are generating interest for applications in catalysis, bioimaging, and drug delivery. In contrast to traditional MPNs coating, in this research, we fabricated novel MPNs microspheres through a facile process in the aqueous solution. The MPNs microspheres are characterized by SEM, TEM, and XPS. The as-prepared microspheres were utilized in the removal of tetracycline (TC), methylene blue (MB), and rhodamine B (RhB). It exhibits high capacity (1331 mg/g) for the adsorption of MB, and a rapid reaction rate (186.9 mg/g/min) for the adsorption of TC.
