摘要：ZrO2-based metal oxides are widely used in heterogeneous catalysis. For heterogeneous catalysis, dispersibility is a challenging job. This article reports a facile synthesis method for preparing ZrO2 -based composite metal oxide fibers based on electrospinning with the assistance of microfluidic chips. The formed fibers have an even distribution of different oxides at the nanometer level. The acidic and alkaline sites of ZrO2 were significantly increased via the doping of SiO2 or MgO. These fibers are the ideal catalytic carriers to load iron oxides for the Fenton reaction. Iron elements are highly and evenly dispersed upon the fibers. The catalysts can degrade 500 ppm dye in solutions more than 90% in 45 min and maintain a high degradation rate after recycling.
