A gold nanopillar array film with high surface area was fabricated by soft lithography and electrodeposition of Polypyrrole(Ppy)/POM(Polyoxometalate) electrode, showing high electrochemical performances. The POM-Ppy/nanopillar electrode delivered high current density because of efficient and fast electron transfer in the nanopillar structures. Furthermore, POM-Ppy/nanopillar electrode had a high electrocatalytic ability for reduction of hydrogen peroxide. Regarding electrochemical characteristics for pseudocapacitive electrodes, the POM-Ppy/nanopillar electrodes was capable of delivering high areal capacitance of 77.0 mF cm−2, high rate performance, and good cycle life of ∼100% retention over 3500 cycles even when bent. |
