本研究第一部份以多元醇的方式合成銀奈米線，並且成功地利用簡便浸泡的製程吸附銀奈米線於碳纖維布表面上，在過氧化氫偵測量測上證明金屬銀的LSPR不需半導體輔助熱電子的傳遞，便可與溶液反應並增益過氧化氫感測。在LSPR激發後，觀察到 過氧化氫的還原電流增加取決於波長和照明強度，推測表面電漿誘發產生的熱電子是增強電催化性能的原因。此外，在過氧化氫的電化學偵測應用中，當LSPR激發時，Ag NWs/CC 電極的過氧化氫檢測度可以提高51％。
第二部分的研究利用金屬銀薄片作為工作電極，在碳酸氫鉀溶液中經過電化學氧化還原過程形成奈米金屬銀(Ag NCs-0)，再將試片浸泡在硫酸中蝕刻十天(Ag NCs-10)，增加金屬銀的表面積與多孔性。利用其 LSPR 效應增益氫還原反應表現。發現照光後過電位可降至 156 mV，塔菲爾斜率達到 79 mV dec-1，並與其他文獻相比後證明實驗中所獲得的 Ag NCs-10 電極在氫還原反應中可以有良好的表現。我們提出了珊瑚狀銀金屬做為電化學分解水產氫的電極，並發現照光後透過 LSPR 產生熱電子可以顯著增強氫還原反應性能。
兩部分的結果說明了單純使用奈米結構且具 LSPR 的金屬銀在電化學還原反應系統能有效地驅使熱電子注入溶液與反應物進行反應，同時產生光電流響應。

In the first part of this study, we successfully used a simple immersion process to adsorb silver nanowires and proved that the LSPR effect can provide hot electron to inject into H2O2 solution without the semiconductor-assistance. After LSPR excitation, it was observed that the reduction current of H2O2 increased depending on the wavelength and illumination intensity. The hot electrons, which were generated by the surface plasman effect, are the reasons for enhancing the electrocatalytic performance.In addition, in H2O2 sensing applications, when LSPR is excited, the H2O2 detection sensitivity of the Ag NWs/CC electrode can be increased by 51%.
The second part of the study used metallic silver foil as the working electrode, and formed nanosilver metal through electrochemical oxidation-reduction process in KHCO3 solution. The LSPR effect is expected to enhance HER performance. It was found that the overpotential could be reduced to 156 mV under illumination, and the Tafel slope reached 79 mV dec-1. In comparison with other literatures,our results were proved that the Ag NCs electrode obtained in the experiment can perform well in the HER reaction. We proposed coral-like silver metal as the electrode for electrochemical reduction of hydrogen in water, and found that the generation of hot electrons through LSPR under
illumination can significantly enhance HER performance.
The results of the two parts show that the bare nanostructured metal with LSPR effect can effectively drive the hot electron injected into solution to react with the reactant in the electrochemical reduction reaction system, while generating a photocurrent response.
