업적 Excellent dye degradation performance of FeSiBP amorphous alloys by Fe…
상세내용 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 advanced
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. Compared
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 efficiency
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.
