A pyridine-based conjugated imprinted polymer as an adsorptive photocatalyst for efficient removal of aqueous Cr(VI).

Abstract

Herein, a designed pyridine-based conjugated imprinted polymer (CIP) was constructed by introducing 4-vinylpyridine (4-VP) via an in situ copolymerization reaction. In addition to the good adsorption performance of Cr(VI), this polymer also showed high efficiency in reducing Cr(VI) in water by photocatalysis. The ingenious design of the polymer not only furnished insight into the enhanced photocatalytic reaction kinetics but also provided a new route for the modification of the molecular skeleton of the conjugated polymer photocatalyst.
