| Abstract: | 本實驗根據DSA（尺寸安定性電極）之構想，藉由使用熱分解法改變熱分解溫度製備不同塗鍍量之氧化釕電極，並將所得氧化釕電極在酸性系統以及鹼性系統中做電化學測試，藉此尋求製作濃氧器陽極材料之適當參數。
使用循環伏安測試得知當氧化釕電極塗鍍量增加時會造成表面活性位置變多使得循環伏安電荷增加，而增加熱處理溫度使得氧化釕結構狀態趨於緻密使得內部活性位置反應使得循環伏安電荷降低，尤其是在450℃與550℃之間的變化最大。
在本實驗中需考慮測試過程的穩定性故使用熱分解溫度450℃製備之氧化釕電極在鹼性系統（1M KOH）中測試，可以獲得穩定以及較佳之實驗數據。
The study of oxygen generating process by using ruthenium oxide materials is a potential anode to be used in a oxygen concentrator devices. The fabrication of dimensional stable anode（DSA）is a thermal decomposition process by using hydrate ruthenium compounds on titanium supported electrode. The characterization of electrodes are observed by surface topographic tools and cyclic voltammetry and the performance of electrodes are measured by current-voltage curves. The active sizes in ruthenium oxide in generating oxygen are thermal treatment dependence and temperature of 450℃ to 550℃ thermal treatments demonstrate good electrode performance in oxygen producing. The stability and life-test of electrodes by using this processes are not established. |
