近年來氣候變遷乃國際間共同關注的議題，而二氧化碳是導致全球氣候加
速暖化的主要溫室氣體，因此減緩「二氧化碳排放」為解決極端氣候問題之核
心。 而用 空氣產生電能的燃料電池則是未來替代能源的一顆新星。金屬空氣燃
料電池顧名思義就是直接把空氣轉換成電能的電池，發電過程中不會產生二氧
化碳，是種極為環保的綠色能源。
在本研究中，成功利用水熱法合成，在高溫高壓下的條件，製備出 GO/C3N4、
GOMXene、 GOMXene/C3N4這三種系列的自主裝氣凝膠。在表面型態、比表
面積分析以及缺陷分析， GOMXene/C3N4有最好 的結果，孔洞的生成多、缺陷
較多 而且又有利於電子傳輸的材料，擁有良好的電催化效果 。
在 ORR/OER檢測中，因為 GOMXene/C3N4氣凝膠融合了 g-C3N4以及 p-MXene的優點，即為支撐物避免堆疊有利孔洞生成，以及有利電子傳遞，將其
電催化效果最 佳 化。而在電子轉移數的測試中，能夠證明本研究所研發之
GOMXene/C3N4氣凝膠是 直接 四電子通路 ，也間接證明 GOMXene/C3N4氣凝
膠 不會產生會腐蝕的物質而去破壞電池。在電化學活性表面積測試中，
GOMXene/C3N4氣凝膠在每平方公分的面積下，有 5.6毫 法拉第電容量，又再
證明出 GOMXene/C3N4擁有良好的電催化性。在充放電測試中，
GOMXene/C3N4和目前發展已趨於穩定的商業 Pt/C之 overpotential相當接近，
而在長時間的充放電測試中， 與 商業 Pt/C相比穩定性較差 ，但是
GOMXene/C3N4的增長率只有大約 18%，還是具有 開發 潛力。

In this study, we successfully used hydrothermal synthesis to prepare GO/C3N4, GOMXene, GOMXene/C3N4 under the conditions of high temperature and high pressure. This is a series of automatic aerogels. According to the analysis, GOMXene/C3N4 has the best results. There are many holes and defects, and it is a material that is conducive to electron transport and has a good electrocatalytic effect.
In the ORR/OER test, because the GOMXene/C3N4 aerogel combines the advantages of g-C3N4 and p-MXene, that is, the support avoids the formation of favorable holes and the favorable electron transfer, which maximizes its electrocatalytic effect . In the test of the electron transfer number, it can prove that the GOMXene/C3N4 aerogel developed by this research is a four-electron pathway, and it also indirectly proves that the GOMXene/C3N4 aerogel does not produce corrosive substances to damage the battery. In the electrochemical active surface area test, GOMXene/C3N4 aerogel has a 5.6 mF/cm2, which again proves that GOMXene/C3N4 has good electrocatalytic properties. In the charge-discharge test, the ΔE of GOMXene/C3N4 is closed to commercial Pt/C. In the continuous charge-discharge test,The ΔE is quite close, while the stability is not as good as the commercial Pt/C. However, the growth rate of GOMXene/C3N4 is only about 18%, and it still has potential development.
