在本研究中，分為兩個不同的部分，包括染料敏化太陽能電池和非酶葡萄糖感測器應用。研究摘要如下所示。
第一部分，奈米鉑立方體通過電化學沉積方法沉積在導電玻璃上，作為染料敏化太陽能電池的對電極。在這項研究中，我們控制晶面的生長，以在室溫下合成單晶PtNCs。通過場發射掃描電子顯微鏡和高解析穿透式電子顯微鏡檢查ECD PtNCs的形態和奈米結晶結構。通過原子力顯微鏡檢查ECD PtNCs的表面粗糙度。通過循環伏安法，Tafel極化和電化學阻抗譜分析了ECD PtNCs的電化學性質。通過質譜儀檢查Pt負載。使用N719染料敏化的二氧化鈦工作電極，碘基電解質和CE組裝DSSC。在AM1.5（100mWcm-2）的照射下檢查具有ECD PtNC CE的DSSC的光電轉換效率（PCE）。該研究中的PtNCs呈現出單晶奈米結構，其可以提高電子遷移率並提高電荷轉移率。在這項工作中，Pt膜和PtNCs的電催化質量活性（MA）分別為1.508和4.088 mAmg-1，PtNCs的MA是商用Pt薄膜的MA的2.71倍。具有脈衝-ECD PtNC CE的DSSC顯示出6.48％的PCE，其高於使用商用Pt薄膜CE的電池（PCE為6.18％）。與通過電子束蒸發方法製造的商用Pt薄膜CE相反，我們的脈衝ECD PtNCs使Pt催化性能最大化為DSSC中的CE。結果表明，PtNCs對DSSCs中的碘化物/三碘化物氧化還原對反應起到了良好的催化作用，為電化學催化應用提供了潛在的策略。

第二部分，非酶葡萄糖感測器由電化學沉積鉑奈米晶體設計和製造，包括鉑奈米球（Pt NS），鉑奈米花瓣（Pt NR）和鉑奈米立方體（Pt NC）在導電玻璃上。通過恆電位或脈衝雙電位沉積進行形態和生長類型的兩種控制，以分別在室溫下合成Pt NS，Pt NR或Pt NC。在三種Pt奈米晶體中，Pt NC對具有單晶結構的葡萄糖（葡萄糖內酯）的氧化顯示出最高的電催化活性。開發的Pt NC電極顯示較快速響應時間（2 s），高靈敏度20.75μA/ mM·cm，檢測限為0.7μM（S / N比= 3）。通過將葡萄糖氧化電位設定為0.1V，Pt NC電極對濃度範圍為0.33至12.50 mM的葡萄糖提供線性依賴性（R2 = 0.99086）。 Pt NC電極顯示出穩定，高靈敏度，低工作氧化電位，低Pt負載，以及在感測葡萄糖時具有快速的安培電流響應，具有優異的重現性和選擇性，具有潛力的非酶葡萄糖感測器應用電極

In this report was divided two different parts that included dye-sensitized solar cell and non-enzymatic biosensor applications. Those study abstract as shown below.
The first part, Platinum nocubes (PtNCs) were deposited onto a fluorine-doped tin oxide glass by electrochemical deposition (ECD) method and utilized as a counter electrode (CE) for dye-sensitized solar cells (DSSCs). In this study, we controlled the growth of the crystalline plane to synthesize the single-crystal PtNCs at room temperature. The morphologies and crystalline nanostructure of the ECD PtNCs were examined by field emission scanning electron microscopy and high-resolution transmission electron microscopy. The surface roughness of the ECD PtNCs was examined by atomic force microscopy. The electrochemical properties of the ECD PtNCs were analyzed by cyclic voltammetry, Tafel polarization, and electrochemical impedance spectra. The Pt loading was examined by inductively coupled plasma mass spectrometry. The DSSCs were assembled via an N719 dye-sensitized titanium dioxide working electrode, an iodine-based electrolyte, and a CE. The photoelectric conversion efficiency (PCE) of the DSSCs with the ECD PtNC CE was examined under the illumination of AM 1.5 (100 mWcm−2). The PtNCs in this study presented a single-crystal nanostructure that can raise the electron mobility to let up the charge-transfer impedance and promote the charge-transfer rate. In this work, the electrocatalytic mass activity (MA) of the Pt film and PtNCs was 1.508 and 4.088 mAmg−1, respectively, and the MA of PtNCs was 2.71 times than that of the Pt film. The DSSCs with the pulse-ECD PtNC CE showed a PCE of 6.48 %, which is higher than the cell using the conventional Pt film CE (a PCE of 6.18 %). In contrast to the conventional Pt film CE which is fabricated by electron beam evaporation method, our pulse-ECD PtNCs maximized the Pt catalytic properties as a CE in DSSCs. The results demonstrated that the PtNCs played a good catalyst for iodide/triiodide redox couple reactions in the DSSCs and provided a potential strategy for electrochemical catalytic applications.
The second part, non-enzymatic glucose sensors were designed and fabricated by electrochemical deposited platinum nano-crystals, including Platinum nanosphere (Pt NS), Platinum nanorose (Pt NR), and Platinum nanocubes (Pt NC) on fluorine-doped tin oxide glass. The control of the morphologies and growth types was conducted by either potentiostatic or pulse-mode potentiostatic deposition for synthesizing Pt NS, Pt NR, or Pt NC, respectively, at room temperature. Among three Pt nano-crystals, The Pt NC displayed the highest electrocatalytic activity to oxidation of glucose (glucolactone) owning to the single crystalline structure. The developed Pt NC sensor showed a fast response time (2 s), a high sensitivity of 20.75 μA/mM·cm, and a detection limit of 0.7μM (at S/N ratio = 3). By setting glucose oxidation potential to 0.1 V, the Pt NC electrode provided a linear dependence (R2 =0.99086) to glucose in a concentration range from 0.33 to 12.50 mM. The Pt NC electrodes showed stable, highly sensitive, low working oxidation potential, low loading of Pt, and rapid amperometric response in sensing glucose with excellent reproducibility and selectivity, possessing a great potential for non-enzymatic glucose sensing applications.
