本研究目的為找出最適化微波熱處理條件的觸媒應用在全電池陰極端上，在 電化學分析中，700 W 和熱處理 4 min 在五個實驗條件觸媒中擁有高達 3.96 的 電子轉移數，非常接近完美四個電子轉移數。
由 X 光繞射光譜圖分析得知，從 700 W 和熱處理 3 min 開始至 700 W 和熱 處理 4 min，由硝酸鐵、尿素和碳材 BP2000 混合形成的特徵峰逐漸瓦裂解形成 新的 Fe-Nx-Cy 鍵結，更清楚的結果可以由 X 光光電子能譜儀分析看出每個微波 處理條件下的氮化學鍵結都有些微不同，經由分峰可以將形成的氮化學鍵結大致 歸類為四類，其中 700 W 和熱處理 3 min 的氮鍵結和 700 W 和熱處理 1 min、
700 W 和熱處理 2 min 相比較下出現變化，已經不是尿素的衍生物所構成的鍵 結，而是由 Quaternary-type nitrogen 和 pyrrolic-type nitrogen 組成，依據文獻指 出 大 量 的 Quaternary-type nitrogen 結 構 能 提 升 導 電 度 ， 證 明 擁 有 100%
Quaternary-type nitrogen 氮成分的 700 W 和熱處理 4 min 成為導電度最佳的材 料。
又從 X 光吸收光譜分析中可以發現，縱然 XANES 指出 700 W 和熱處理 1 min 到 700 W 和熱處理 5 min 的鐵氧化態都以+3 價存在，EXAFS 圖譜顯示 700 W 和熱處理 3 min 和 700 W 和熱處理 4 min 產生了 700 W 和熱處理 1 min 與 700 W 和熱處理 2 min 沒有形成的 Fe-N2鍵結，而 700 W 和熱處理 4 min 的 Fe-N2鍵結 所佔的比例又比 700 W 和熱處理 3 min 多，導致 700 W 和熱處理 4 min 的氧氣 還原性最佳。
最後，將不同熱處理條件下的觸媒作為全電池的陰極做全電池測試，測試後 發現 700 W 和熱處理 4 min 條件下的全電池，其最大功率密度有 350 mW cm-2， 開路電壓也有 0.95 V，最大電流密度也有 1300 mA cm-2，為所有條件之全電池裡 最優良的。將電池做定電位 0.4V 之 150 小時長時間穩定性測試，圖譜顯示其電 流密度並無大幅改變，電池穩定性極佳。
