Magnetic Functional Heterojunction Reactors with 3D Specific Recognition: Towards Selective Photocatalysis and Synergistic Photodegradation in Binary Antibiotic Solution
We report on the development of emerging magnetic functional heterojunction reactors with three-dimensional (3D) specific recognition. Upon synthesis by engineering the surface imprinting technique and the visible light-induced polymerization method, the developed magnetic functional heterojunction reactors not only possess emblematic conductive polymer POPD, but also equipped with the imprinted cavities in corresponding 3D specific recognition outer layer. POPD forms a heterojunction with TiO2 and remarkably enhanced the photocatalytic activity from our experimental data consolidation. Owing to the presence of imprinted cavities, the magnetic functional heterojunction reactors exhibited excellent 3D specific recognition ability for selective degradation of danofloxacin mesylate in the binary antibiotic solution. Importantly, upon in-depth understanding of the proposed mechanisms, the systematic and complementary modes pertaining to the electron transfer, 3D specific recognition, and the selective photodegradation, as well as the photodegradation pathways mechanism are methodically discussed and exemplified. The present work provides a new path and demonstrates that the 3D specific recognition ability can be utilized to selectively degrade the specific organic pollutant in widely practical environmental protection applications.
