為因應氣候變遷，開發乾淨能源已成趨勢。直接甲醇燃料電池具有低汙染、高效率、低噪音、免充電、進料來源廣且燃料儲存容易等優勢，在攜帶型裝置的應用上有極高發展潛力。然而甲醇氧化反應速率遠低於氫氣氧化反應速率，同時白金觸媒昂貴且易毒化，阻礙其商業化發展。本研究混合硼酸、鉑釕前驅物與氧化石墨烯以水熱法合成甲醇氧化觸媒，探討氧化石墨烯在還原前靜置於空氣的時間、不同還原方法、不同硼酸重量、不同水熱還原溫度、不同水熱還原時間等條件對觸媒特性之影響，並求得最佳製備條件以得最高甲醇氧化活性。
XRD結果顯示，氧化石墨烯在還原前靜置於空氣中的時間會影響其層間距。新鮮製備的氧化石墨烯層間距(0.850 nm)大於靜置3個月的氧化石墨烯 (0.803 nm)。加入15.4倍氧化石墨烯重量的硼酸，在180 oC下加熱5小時合成觸媒進行電化學測試，電化學活性面積與甲醇氧化比活性皆隨靜置時間增加而下降。
使用靜置3個月的氧化石墨烯，經由不同還原方法合成觸媒，電化學測試結果顯示同時還原氧化石墨烯與鉑釕合成觸媒，電化學活性面積為先水熱還原氧化石墨烯再擔載鉑釕之觸媒的2.09倍，比活性為3.06倍。
使用新鮮製備的氧化石墨烯合成觸媒，在硼酸重量為15.4倍氧化石墨烯重量、水熱溫度為180 oC、加熱時間為5小時的條件下，白金觸媒在0.4V (vs. Ag/AgCl)有最大質量活性240 A/gPt及比活性1.46 s-1，為未在製程中加入硼酸所製觸媒的2.73倍及1.92倍，代表加入硼酸不僅能降低白金奈米粒徑、提升觸媒電化學活性面積，更在本質上提升甲醇氧化比活性。
XPS結果顯示無論有無硼酸加入，皆無硼摻雜情形，然而隨著硼酸重量增加，碳材結構中C-O官能基比例下降，推測硼酸加入有助於移除氧化石墨烯中C-O官能基，降低碳材表面電荷傳輸阻力，進而提升甲醇氧化比活性。

PtRu/rGO were synthesized by 1-step reduction or 2-step reduction. The highest MOR activity and specific activity was obtained when PtRu/rGO was synthesized by fresh GO and 1-step reduction, with the boric acid to GO weight ratio equaled 15.4 and hydrothermal condition was 180 oC for 5 hours. Regardless of addition of boric acid, there were no boron doping in carbon materials. However, contents of C-O functional groups decreased as the amounts of boric acid in the process increased, which may lead to lower charge transfer resistance and intrinsically increase the MOR activity.
