Green Fabrication of Tannic Acid-Inspired Magnetic Composite Nanoparticles toward Cationic Dye Capture and Selective Degradation.

ABSTRACT: An environmental strategy for developing sustainable materials presents an attractive prospect for wastewater remediation. Herein, a facile, green, and economical strategy is proposed to fabricate magnetic composite nanoparticles (NPs) toward cationic dye adsorption and selective degradation. To prepare the composite TiO₂-PEI-TA@Fe₃O₄ NPs, tannic acid (TA) and polyethyleneimine (PEI) were first used to decorate Fe₃O₄ NPs at aqueous solution, and then TiO₂ NPs were anchored onto the surfaces of Fe₃O₄ NPs based on the catecholamine chemistry. The chemical composition and microstructure of the obtained NPs were systematically characterized. The NPs not only exhibited adsorption ability for the cationic dye
