Electro-oxidation of ethylene glycol on nanoporous Ti-Cu amorphous alloy

► Nanoporous Ti-Cu amorphous alloy exhibits apparent EG electrocatalytic ability EG electro-oxidation occurs more easily in alkaline medium than in acid medium. ► In acid medium, heat treatment plays an enhancing role towards EG oxidation. ► In alkaline medium, heat treatment has opposite effect below and above 0.1 V.
