Amorphous alloys are being newly applied in wastewater treatment because of their unique atomic packing structure.They possess excellent degradation efficiency,stability and reusability.In this work,Fe_(80)Si_(10)B_(10) and Fe_(83)Si_(5)B_(8)P_(4) amorphous ribbons exhibited ad-vanced catalytic performance for the degradation of Methyl Blue(MB)and Rhodamine B(RhB)dyes,and the color removal reach nearly 100%within 11 min for both the dyes.Com-pared with the Fe_(80)Si_(10)B_(10) amorphous ribbon,the Fe_(83)Si_(5)B_(8)P_(4) ribbon showed higher degra-dation efficiency due to its lower reaction activation energy,higher electron transfer ability and higher Fe content,and the formation of the galvanic cell between the strong Fe-P bonds and the weak Fe-B bonds.It also exhibited high stability and reusability.The degradation ef-ficiency was improved when the appropriate concentration of H_(2)O_(2) is added.As regards the pH,high degradation efficiency was observed in acidic MB solution,but it decreased as the pH increased up to pH 7.The application of the electro-Fenton-like process is discussed,which can effectively improve the degradation performance in a nearly natural solution.This study presents a high efficiency low-cost catalyst for synthetic dye degradation and expands the functional applications of Fe-based amorphous alloys.
