本實驗利用簡易且低成本的電化學方法製備鈀顆粒修飾的泡沫銅電極(Pd/Cu foam)再結合陽極氧化法製出鈀/氧化銅複合式電極(Pd/CuO/Cu foam)並將其應用在於葡萄糖感測。使用具有三維網絡結構的泡沫銅(Cu foam)作為基板以提高催化表面積。
第一個部分著重在鈀修飾電極條件最適化，透過改變不同螯合劑、螯合劑濃度；不同沉積方法、沉積時間；不同電解液酸鹼值及是否需要退火為變因並使用X繞射分析儀(XRD)、掃描式電子顯微鏡(SEM)與循環伏安法(CV)做分析鑑定。適當的三乙醇胺(TEA)濃度可以有效抑制鈀離子還原並使鈀顆粒形成類似花狀的結構；電解液pH=2時製備出的電極對葡萄糖靈敏度最高。
結束鈀顆粒的最優化條件探討後，第二部分著重在基板上。將泡沫銅氧化生成氫氧化銅及氧化銅。以陽極氧化時間、陽極氧化電流、鹼液濃度及鈀顆粒沉積時間為改良參數，透過X繞射分析儀、掃描式電子顯微鏡、能量分散式分析光譜儀(EDS)與計時安培法分析(CA)鑑定。其中氧化銅後對葡萄糖的敏感度最高，將少量的鈀沉積在氧化銅上可增加修飾電極對葡萄糖的靈敏度。
經由以上實驗參數優化得到之鈀/氧化銅複合式電極其靈敏度為9.6141 mA cm-2 mM-1；偵測極限為18.5 µM。

In this work, Pd/Cu foam electrode and Pd/CuO/Cu foam electrode were prepared by open circuit potential, chronopotentiometry and anodic oxidation. The prepared electrodes have been characterized by XRD, SEM, EDS and CV. Optimization of the experimental parameters inludes the concentration of Triethanolamine(TEA), the pH of Pd2+ solution, concentration of NaOH, the anodization current and the anodization duration. The addition of TEA makes the palladium particles present a multi-layered flower-like structure, which helps increase the catalytic surface area.The Pd/Cu foam deposited at pH=2 is the most sensitive to glucose.
The Pd/CuO/Cu foam electrode is used as a sensor material for detecting glucose. Compared with Pd/Cu foam 4.947 mA cm-2 mM-1 and CuO/Cu foam 6.261 mA cm-2 mM-1, Pd/CuO/Cu foam has the highest sensitivity, which is 8.752 mA cm-2 mM-1. The detection limit of the Pd/CuO/Cu foam electrode is estimated to be 18.5 μM and and it is not interfered by uric acid(UA), ascorbic acid(AA) and dopamine(DA).
