Direct ethylene glycol fuel cells represent promising advanced portable energy storage and conversion devices,which can be well applied to serve as advanced sustainable energy technology to overcome the formidable challenges ofecological crisis and environmental pollution. However, many drawbacks of the newly established catalysts such as poorcorrosion resistance and antipoisoning make them exhibit limited electrocatalytic performances. For addressing these issues, weherein combined both morphological and component advantages to engineer an advanced Au−Ag−Cu trimetallicelectrocataystwith fascinating hollow nanoflowers structures. By virtue of such unique structure, the as-obtained Au−Ag−Cu hollownanoflowers displayed unprecedentedly excellent electrocatalytic activity toward ethylene glycol oxidation with the highest massactivity of 5493.4 mA mgAu −1, 5.9-fold enhancement than that of pure Au. We postulate that the strategy and electrocatalystsweengineered in this work will greatly boost the commercial development of fuel cell technologies.
