The outstanding performance of ball-milled Co-based metallic glass powder in degrading dye wastewater is reported. Higher activity and lower mass loss of the Co-based metallic glass solve the insurmountable problems in conventional zero-valent metal technology to treat environmental contaminants. Acid orange II in aqueous solution was completely degraded in two minutes by the Co-based metallic glass powder, which is much faster than the treatment by the widely studied zero-valent iron powder. The coordinatively unsaturated local structure of the metallic glass responds to the catalysis for degradation, resulting in very low mass loss. The Co-based metallic is the most efficient material for azo dye degradation reported thus far, and will promote the practical application of metallic glass as functional material.
