Abstract In this work, four kinds of Fe80+2xP10-xC10-x(x=0,1,2,3, at%) amorphous alloy ribbons with different Fe contents were prepared. The catalytic degradation of methylene blue (MB) solution by Fe80+2xP10-xC10-x(x=0,1,2,3, at%) amorphous alloy ribbons was studied by Fenton-like reaction. The results show that Fe-P-C amorphous alloy ribbons exhibit excellent degradation performance of MB solution by Fenton-like reaction, and the higher the iron content, the better the degradation performance. However, when the iron content exceeds 82at%, the effect of iron content on the degradation performance is not obvious.The surface morphology observation showed that with the increase of Fe content, the surface of the Fe-P-C amorphous ribbon after reaction showed a more porous structure, which was beneficial to obtain high degradation efficiency. The cyclic degradation test shows that the four Fe-P-C amorphous alloys with different iron contents have little difference and have long service life, which may be related to the formation of surface morphology with loose lamellar structure and 3D flower-like grid structure during the degradation process. The results of X-ray electron energy spectrum analysis showed that the different Fe content did not affect the degradation reaction mechanism of Fe-P-C amorphous alloy.
