“…When the pH is between 3.3 and 7.7, TC presents in the form of a zwitterionic state (TCH 2 ± ). TC exists as the anionic state (TCH – and TCH 2– ) at pH > 7.7. , In addition, the UV–vis absorbance of TC exhibits a red shift in the alkaline condition due to the appearance of a carboxylic ester group. Moreover, zeta potentials of FTTS-2 in various pH values were also measured to determine the surface charge of the photocatalyst, as depicted in Figure d.…”

To achieve a selective degradation of pollutants in a water body, 3D/1D magnetic molecularly imprinted fibers Fe 3 O 4 @ TiO 2 /TC-TiO 2 /SiO 2 were fabricated by an electrospinning method. The molecularly imprinted layer was successfully prepared by a direct imprinting method using TiO 2 as a functional monomer. Fe 3 O 4 facilitates the catalyst recovery and light utilization. The as-prepared fibrous photocatalyst has a large specific surface area of 132.4 m 2 /g. The successful generation of imprinted sites was proven by various characterizations. The weak interaction between the inorganic functional monomer and tetracycline (TC) was determined to be van der Waals force and hydrogen bonds by the IGMH isosurface theory. The construction of the 3D/1D homojunction of molecularly imprinted materials is beneficial to charge transfer. The asprepared photocatalyst exhibits a high selectivity coefficient α = 737.38 competing with RhB. The TC removal efficiency reached 100% within only 20 min. In addition, the possible degradation pathway and the degradation mechanism are reasonably proposed. This work not only provides an in-depth mechanism of the weak interaction between the inorganic molecularly imprinted functional monomer and pollutant molecules but also offers new thoughts on the fabrication of photocatalysts for the effective and selective treatment of pollutants in water bodies.
