Abstract: Degradation of organic contaminants in industrial wastewaters has become a worldwide conundrum and attracted extensive attention. In this paper, we report a flexible grid structure with uniform mesh fabricated by plain weaving melt-extracted Fe80B20 glassy micro-wires, and the produced wire grid with a dosage of 0.3 g/L can completely degrade 0.2 g/L DB 15 azo dyes for <30 min at room temperature. The calculated degradation efficiency of the sample is approximately 4.3 min, 2.1 times faster than that of the Fe80B20 glassy ribbons and 28 times for commercial pure Fe powders. The enhanced degradation performance is primarily attributed to the uniform grid structure with high internal surface area in addition to the intrinsic activity of metallic glasses. Our findings not only provide high-performance candidate for degrading and filtering wastewater with organic pollutant simultaneously, but also promote the practical applications of metallic glasses as functional materials.
