Advancing the intrinsic catalytic performances of electrocatalysts is believed to be an efficient approach for alleviating the energy crisis and environmental pollution. However, many drawbacks of the newly established catalysts such as large size, poor corrosion resistance, and anti‐poisoning make them exhibit limited electrocatalytic performances. To address these challenges, we herein embody the advantages of both composition and morphology to successfully fabricate self‐supported worm‐like PdAg nanoflowers (PdAg NFs) with the assistance of cetyltrimethylammonium bromide. Such special PdAg NFs with a high active surface area of 42.36 m 2 g −1 display much better electrocatalytic performances with mass and specific activities of 5545 mA mg −1 and 12.82 mA cm −2 towards ethylene glycol oxidation, which are 6.9 and 2.1 times higher than that of commercial Pd/C, respectively. Our efforts in this work may open up a new way to maximize the electrocatalytic performance of catalysts by designing and adjusting their morphologies. We also trust that the electrocatalysts fabricated in this work can be applied as potential anodic catalysts and beyond.
