摘要

Excessive consumption of electrical energy has hampered the widespread application of electrochemical technology for degradation of various contaminants.In this paper,a Fe-based metallic glass (MG) was demonstrated as a new type ofelectrocatalyst to effectively and economically degrade an azo dye.In comparison to other typical electrodes,Fe-based MG electrodes exhibit a minimized degradation time,and the specific energy is 4-6 orders of magnitude lower than that of dimensionally stable anode (DSA),metal-like boron-doped diamond (BDD) and other electrodes.As sacrificial electrode materials,Fe-based MGs have less specific electrode mass consumption than iron electrodes.The use of Fe-based MGs will promote the practical application of electrochemical technology and the use of MGs as functional materials.
