Well‐defined three‐dimensional (3D) PdCu bimetallic alloy nanosponges (BANs) with highly porous structure was reported through a rapid and general strategy. Significantly, the as‐prepared PdCu BANs exhibited greatly enhanced activity and stability than commercial Pd/C catalyst towards ethanol electrooxidation in an alkaline medium. Pd 1 Cu 1 shows higher active area and better electrocatalytic activity than Pd 1 Cu 2 and Pd 2 Cu 1 . This result demonstrates the potential of applying these PdCu BANs as effective electrocatalysts for direct alcohol fuel cells (DAFCs).
