Title: | Fe-based metallic glass catalyst with nanoporous surface for azo dye degradation | Authors: | Deng, Z Zhang, XH Chan, KC Liu, L Li, T |
Issue Date: | May-2017 | Source: | Chemosphere, May 2017, v. 174, p. 76-81 | Abstract: | In this work, porous structures were introduced to the surface of Fe-based metallic glass ribbons for the first time by chemical treatment in order to increase the catalytic activity in the degradation of azo dyes. 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-Si-B-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. | Keywords: | Azo dyes degradation Catalytic properties Fe-based metallic glasses Nanoporous surface |
