dc.description.abstract本研究中,我們利用雙電極電化學沉積在室溫下 ,將鉑奈米樹狀和奈米花狀結構成長在自製且低成本的可撓式碳電極表面上。透過調控界面活性劑以及助導劑的濃度,來控制其在電鍍過程中的晶面成長方向 進而得到不同的鉑奈米結構,且深入探討不同變因對鉑奈米結構之影響,以及可能成長機制之推測。 本研究發現,奈米樹狀鉑擁有27.86 m2/g 電化學活性表面積,而奈米花狀鉑則是擁有高的電化學活性表面積 54.15 m2/g。另外,透過甲醇氧化反應,我們可以得到其起始電位分別是0.460 V和0.459 V。zh_TW
dc.description.abstractIn 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.en_US
