摘要：

This work presents the synthesis of iron oxide nanocatalysts supported on mesoporous Al-SBA-15 by using a continuous-flow setup. The magnetic nanomaterials were tested as catalysts in the oxidative disruption of isoeugenol by using hydrogen peroxide as a green oxidant, featuring high activities (63-88% conversion) and good selectivities to vanillin (44-68%). The catalytic systems exhibited good magnetic properties when synthesized under continuous-flow conditions at temperatures not exceeding 190 degrees C. The use of microwave irradiation significantly reduced times of reaction drastically but exerted negative effects on catalyst reusability.
