Preparation of Hollow Magnetic Porous Zirconia Fibers as Effective Catalyst Carriers for Fenton Reaction

Abstract

This article reports a facile synthetic method for preparing hollow magnetic porous Zirconia fibers based on electrospinning and its application as a carrier for Fenton reaction. First, we prepared the uniform hollow porous ZrO2 nanofibers by employing the coaxial electrospinning technique followed by subsequent heat treatment. By adding magnetic particles to the inner electrospinning precursor solution, magnetic nanoparticles were conveniently assembled into hollow ZrO2 fibers. The hollow magnetic porous zirconia fibers have a BET specific surface area of 34.70 m2 g-1 and a pore volume of 0.18 cm3 g-1. At the same time, the catalyst was an excellent carrier to load iron ions for Fenton reaction. These iron-loaded fibers exhibit excellent catalytic performance when considering the degradation of organic pollution, such as methylene blue and phenol. The methylene blue with different initial concentration (from 50 ppm to 300 ppm) can be effectively degraded (99% to 90%). More importantly, the fibers have unique magnetic properties and can be easily removed and reused, showing great potential for practical applications.
