摘要：

The high-efficient degrading ability of Fe BC amorphous ribbons toward acid orange 7(AO7) via redox reactions is reported and compared with that of Fe PC amorphous ribbons. The time required for degrading50% of AO7 using Fe BC amorphous ribbons is only 1/3 of that using Fe PC amorphous ribbons. In the Fe BC amorphous matrix, galvanic cell structures are formed between the Fe-B and Fe-C bonds because of the large difference in their bonding strengths, which contributes to the low reaction activation energy and the high degrading efficiency of Fe BC amorphous ribbons. The extremely long service life of Fe BC amorphous ribbons comes from the progressive formation of 3 D porous nanosheet networks that allow more efficient mass transport and a larger specific surface area. The Fe BC amorphous ribbons show a satisfying degrading ability in not only acidic but also neutral and weak alkaline AO7 solutions. This work provides an effective and environmental-friendly material for degrading azo dyes.
