Abstract

The results show that etching treatment in an HF solution with a volume concentration of 20% for 40 min leads to a porous structure on the Fe[sbnd]Si[sbnd]B[sbnd]Nb metallic glass with a dramatic increase in the specific surface area by 25 times. The much higher specific surface area of the porous ribbons greatly improves the catalytic activity in the degradation of Direct Blue 15 when compared with as-spun metallic ribbons.
