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.

微流控芯片辅助制备ZrO _2基催化纤维

基于ZrO ₂的金属氧化物广泛用于非均相催化中。对于非均相催化，分散性是一项艰巨的工作。本文报道了一种在微流控芯片的辅助下基于静电纺丝制备ZrO ₂基复合金属氧化物纤维的简便合成方法。所形成的纤维在纳米水平上具有不同氧化物的均匀分布。通过掺杂SiO _2可以显着增加ZrO ₂的酸性和碱性位或氧化镁。这些纤维是负载芬顿反应的氧化铁的理想催化载体。铁元素高度均匀地分散在纤维上。催化剂可在45分钟内降解90％以上的溶液中的500 ppm染料，并在回收后保持较高的降解率。
