碩士 === 國立交通大學 === 應用化學系碩博士班 === 104 === In this study, we deposited Pt nanodendrites (Pt NDs) and Pt nanoflowers (Pt NFs) on a flexible carbon substrate in simple two-electrode system at room temperature. By controlling the concentration of surfactant and electric aid agent, we obtained various Pt structures. Because the surfactant and electric aid agent assist the Pt growth on special orientation, we discussed these factors on Pt structures in detail. Then, we proposed the possible growth mechanism for Pt . In the hydrogen electrosorption test, we got the Pt NDs with electrochemical active surface area (ECSA) 27.86 m2/g, and the Pt NFs with ECSA 54.15 m2/g. The ECSA of commercial Pt/C is around 43.80 m2/g. In methanol oxidation reaction test, the onset potentials of Pt NDs and Pt NFs are 0.460 V and 0.459 V, respectively.
