Abstract
Fe-based amorphous alloy was widely concerned in the field of wastewater treatment because of its nanoporous structure, which has higher reactivity activity. However, as it is easy to get oxidative poisoning, its long-term reactivity activity is restricted. A uniform nanoporous layer has been synthesized by mechanical attrition and dealloying on the surface of Fe76Si9B10P5 amorphous alloy powders in this work. In the test of catalytic performance, due to nanoporous structure, Fe0/FeⅡ/FeⅢ are involved in the Fenton process at the same time. The Fenton reaction was further catalyzed to generate more active group · OH; therefore, the degradation rate reaches 99.8% within 60 min. This coexistence of Fe0/FeII/FeIII persisted after five cycles of the catalytic reaction, indicating the excellent catalytic stability of the catalyst. Using this tunable pretreatment method for surface activation, novel applications for metallic glasses can be developed.
