Applied Surface Science, Vol.589, ISSN No: 0169-4332.
Electrochemically deposited porous film of poly(aniline) (PANI) on stainless steel (SS) current collector is employed as the support for electrodeposition of platinum (Pt). PANI facilitates the formation of Pt nanoflowers with an enhanced electrochemically active surface area compared with sub-micron size Pt particles deposited on the bare SS electrode. Hence, a new concept Pt nanoflower-PANI electrode materials with synchronization between redox mode in PANI and double-layer mode of charge storage in Pt nanoflower is discussed. Remarkably, Pt is distributed like a nano-flower on the surface of PANI and prevents PANI from stripping during the charge-discharge process, thereby minimizing the issue of stripping in conducting polymer-based electrodes.
