本論文研究利用化學氣相沉積製備氧化釕奈米桿，與層溫脫附圖譜瞭解奈米桿對氧、甲醇、乙醇、甲酸的吸附特性。由於氧化釕奈米桿似乎是極佳的表面反應氧供應者，我們進一步研究Pt/RuO2NR的電化學觸媒特性。電化學觸媒活性的初步測試用循環伏安法在甲醇、乙醇、甲酸、乙二醇水溶液中進行，甲酸溶液內Pt/RuO2NR的活性最佳，因此我們進一步詳細研究甲酸的電化學氧化動力學。
RuO2 奈米桿以一維垂直且緻密的成長在鈮酸鋰(100)單晶上。RuO2奈米桿單晶成長方向為[001]，且奈米桿四周桿面結晶面為(110)面。在層溫脫附實驗中發現，RuO2奈米桿表現出對簡單碳氫化合物分子有強烈的脫氫能力。我們也發現一氧化碳在RuO2表面上有不同的反應路徑，亦產生不同的鍵結能量，並且發現RuO2奈米桿具有氧化一氧化碳成為二氧化碳的能力，層溫脫附的結果說明了RuO2表面氧原子提供協助催化的效果。由Pt/RuO2 奈米桿電極對甲酸電解液的極化曲線中，Tafel slope測量約為126 mVdec-1。實驗導向為變化不同甲酸濃度與不同硫酸濃度，求証出甲酸濃度對反應速率式影響階數為0.58，而氫離子濃度影響階數為-1。甲酸陽極氧化依溫度的影響變化，即符合Arrhenius 方程式，即可求出甲酸活化能19.5 kJ/mol。

We have investigated the preparation of RuO2 nanorods (RuO2NR) via chemical vapor deposition and their adsorption characteristics on oxygen, methanol, ethanol, and formic acid using the temperature programmed desorption TPD spectroscopy. Since the RuO2NR appears to be an excellent oxygen reservoir for surface reaction, we further explore the electrocatalytic properties of Pt/RuO2NR. Preliminary test on catalytic activity is done on methanol, ethanol, formic acid, and ethylene glycol using cyclic voltammetry CV, and the Pt/RuO2NR demonstrates the highest activity in formic acid. Hence the electrochemical reaction kinetics of formic acid oxidation on Pt/RuO2NR is studied in details.
One dimensional vertically aligned RuO2NR is grown epitaxially and densely on LiNbO3(100). The growth direction is [001] of RuO2 crystal, the crystal plane of nanorods side wall is (110). In the TPD experiments, RuO2NR exhibits strong capability in depriving hydrogen from the simple hydrocarbons. We also find that different reaction paths for the carbon monoxides that bind differently on surface, and also carbon monoxide converting to carbon dioxide. The TPD results indicate the surface oxygen assists in converting carbon monoxide to dioxide. The polarization curve of Pt/RuO2NR electrode is recorded in the aqueous solution of formic acid. The Tafel slope is measured around 126 mVdec-1. Experiments conducted in the solutions of various formic acid and sulfuric acid concentrations indicate that the order of formic acid concentration in the rate equation is 0.58, while that of hydrogen concentration is -1.0. The temperature dependence of formic acid anodic oxidation is correlated in an Arrhenius-type equation with activation energy 19.5 kJ/mol.
