Activation of peroxymonosulfate by Fe78Si9B13 metallic glass: The influence of crystallization

Abstract

Exploring functional applications as heterogeneous catalysts is an active topic for metallic glasses (MGs). Although recent advances have shown that the MGs with disordered atomic packing structure are indeed having superior catalytic reactivity for wastewater remediation, the catalytic mechanism is not yet clear. Herein, crystallization in melt-spun Fe78Si9B13 glassy ribbons was applied at various annealing temperatures for understanding the catalytic mechanism. The crystalline structures and volume fractions of the crystallized α-Fe in the as-received and annealed glassy ribbons were fully characterized. The results showed that Fe78Si9B13 glassy ribbons with disordered atomic structure pre..
