Building noble metallic nanograins into three‐dimensional architectures with large accessible surface area is of great significance in electrochemical fields. Here, we synthesized pore array architectured silver (pore array‐Ag ) with nanograin size and three‐dimensional arrangement using butterfly‐wing scales as template by electroless deposition method. Efficient electrochemical detection performance was achieved for hydrogen peroxide with a sensitivity of 61.0 μA/(mM cm 2 ) and detection limit of 33 μM. This work presents an exemplary strategy for fabricating elaborate metallic architectures for efficient electrodes by borrowing the structural design wisdom from nature.
