本研究利用氧化石墨烯(Graphene oxide, GO)與三苯基磷(Triphenylphosphine, TPP)透過水熱法及高溫爐還原形成磷摻雜石墨烯(PG)，將之應用於氧氣還原反應(Oxygen reduction reaction, ORR)的研究。並利用旋轉環-盤電極(Rotating ring-disk electrode, RRDE)計算電子轉移數，藉此了解ORR的機制。
研究分為兩部分。第一部分陡升陡降途徑實驗 (PSA/D)中，控制(A).三苯基磷(TPP)比例，(C).微波功率，(E).燒結溫度，(F).CNT，有效控制電子轉移數從 3.91至2.88，並命名為PG(3.91)、PG(3.75)、PG(3.51)、PG(3.13)、PG(2.88)。在材料鑑定上，以 XPS 分析磷參雜結構，及透過 SEM觀察形態，並藉由拉曼光譜及XRD分析 P-rGO的缺陷程度，且藉由BET(比表面積儀)證實PG(3.91)擁有最高的表面積453.2 m2/g，證明比表面積的提升與電子轉移數有正相關。
第二部分利用PG(3.91)作為鋅空氣電池之應用，其最大功率密度118.67mW cm-2出現在電流密度221 mA cm-2，其表現比起許多先前的文獻都還要優異。本研究也利用PG(2.88)在0V (vs. RHE) 最高效率操作電位下一小時，產生H2O2濃度(29.4 mg L-1)。上述結果證明了P-rGO可成為鋅空氣電池陰極及產生過氧化氫反應的催化劑。

This thesis mainly focuses on the microwave and annealing synthesis and fabrication of Phosphorus-doped reduced graphene oxide (P-rGO) and its application on oxygen reduction reaction (ORR). The rotating ring-disk electrode (RRDE) voltammetry was applied to calculate electron transfer numbers to study ORR.
In the first part, 26-2 factorial design of experiments and path of steepest ascent/descent (PSA/PSD) experiments were applied , six factors including: (A). triphenylphosphine ratio, (B). annealing temperature(°C), (C). microwave power(W) ,(D) microwave time(min), (E). annealing temperature and (F). CNT concentration were controlled in order to obtain the optimal values of electron transfer number for ORR. The highest electron transfer number was 3.91, whereas the lowest one was near 2.88. The samples were assigned as PG(3.91), PG(3.75), PG(3.51), PG(3.13), PG(2.88).
The structures and distributions of phosphorus doped onto r-GO were examined by the x-ray photoelectron spectroscopic (XPS) and EDX analysis. The layer-by-layer morphology and the high degree of defects of P-rGO were characterized by scanning electron microscopy (SEM) , and Raman spectroscopy.
In the second part, PG (3.91) was utilized for zinc air battery. The maxium power density (118.67mW cm-2) occurs at current density (221 mA cm-2). Moreover, PG (2.88) was used for H2O2 generation. The maxium H2O2 concentration (29.4 mg L-1) appears at 0V (vs. RHE) operating for 1hr. These results confirm P-rGO can be the excellent catalyst for zinc air battery and H2O2 generation.
