FeSiB metallic glass using pulsed laser processing is proved to show excellent catalytic performance in wastewater treatment for the first time by decolorizing and mineralizing reactive red 195.Pulsed laser can effectively improve the thermodynamic properties,surface photothermal conversion and hydrophilic-ity of catalyst.Compared with homogeneous FeSiB catalyst,heterogeneity a-Fe/FeSiB exhibits a high k value,strong TOC removal rate and low activation energy.Theoretical calculations indicate that the ex-cellent catalytic performance of heterogeneity catalyst is attributed to its unique nanoscale biphasic dis-order structure,resulting the energy barrier of the rate-determining-steps of the conversion of S2O82-to SO4-·is reduced from 2.20 to 1.52 eV.The reusability test of heterogeneity catalyst also shows that the abnormal recovery phenomenon of decolorization efficiency at the 19th cycle owing to its unique self-renewing.This study reveals that a nanoscale biphasic disorder structure is a new strategy for obtaining high catalytic rate and durability.
