Preparation of inorganic-framework molecularly imprinted TiO₂/SiO₂ nanofibers by one-step electrospinning and their highly selective photodegradation

Abstract

The TiO2/SiO2 hybrid fibers were successfully prepared by a simple electrospinning method and modified by direct molecular imprinting. The as-prepared samples exhibit excellent selectivity and photocatalytic performance.

3D/1D Fe3O4@TiO2/TC-TiO2/SiO2 Magnetic Inorganic-Framework Molecularly Imprinted Fibers for Targeted Photodegradation

“…To achieve the successful combination, four types of preparation methods were developed, described as follows: (i) adding templates during electrospinning, (ii) coating molecularly imprinted layer onto the fibers, (iii) electrospinning on templates-based collector, and (iv) dispersing molecularly imprinted particles into fibers . In our previous work, inorganic framework molecularly imprinted TiO 2 /SiO 2 hybrid fibers were fabricated by the first method . However, the traditional electrospinning process of TiO 2 usually adds acetic acid to inhibit the hydrolysis of the titanium source, resulting in the structural change of contaminants that are sensitive to pH and deactivating the imprinting chamber.…”
