Abstract

Exploring new alloys with high efficiency in degrading organic pollutants in aqueous solutions is of wide interests. Here, we report that the nanocrystallized Fe^82.65Si⁴B¹²Cu^1.35 alloy exhibits higher efficiency in decolorizing azo dye solutions compared to its amorphous counterpart. The increased efficiency is attributed to the formation of numerous microbatteries between the α-Fe(Si) and Fe²B nanocrystalline phases, which exhibit different corrosion potentials. These results suggest that nanocrystallized Fe-based amorphous composites hold promising application potential in degrading azo dyes solutions.
