Heat-Activated Persulfate by Fe-Based Metallic Glass: A Comparative Study of Two Dyes

In this work, the heat-activated persulfate (PS) in the presence of Fe 78 Si 9 B 13 metallic glasses (MGs) shows an extremely difference in degradation of azo dye and triarylmethane dye, where Fe 78 Si 9 B 13 MGs exhibits a superior activation ability for PS with assistance of heat leading to the fast removal of two dyes. The structural features of Fe 78 Si 9 B 13 MGs are firstly characterized by X-ray diffraction (XRD) and differential scanning...
