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 *** time required for degrading50%of AO7 using Fe BC amorphous ribbons is only 1/3 of that using Fe PC amorphous *** 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 *** 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 *** Fe BC amorphous ribbons show a satisfying degrading ability in not only acidic but also neutral and weak alkaline AO7 *** work provides an effective and environmental-friendly material for degrading azo dyes.
