Professor Ronald W. Fawcett of the University of California-Davis is supported by the Analytical and Surface Chemistry Program in the Division of Chemistry to study the cathodic oxygen reduction reaction, and the anodic methanol oxidation reaction. The reactions will be investigated using decorated catalysts in aprotic media to separate the effects due to interactions of the reactant with the catalyst surface from effects due to reactive intermediates arising from water. The experimental work will involve electrochemical tecniques, including cyclic voltammetry and faradaic admittance studies. In addition, FTIR spectroscopy will be used to identify reactants and reactant intermediates at the electrode / solution interface. Oxygen reduction occurs at the cathode of every fuel cell and methanol oxidation to carbon dioxide and water is an important area of fuel cell research. Students will be trained in this important area of alternative energy research.

罗纳德W.加州大学戴维斯分校的福塞特得到化学系分析和表面化学项目的支持，研究阴极氧还原反应和阳极甲醇氧化反应。 将使用修饰的催化剂在非质子介质中的反应进行研究，以分离由于反应物与催化剂表面的相互作用的影响，由于反应中间体产生的水的影响。 实验工作将涉及电化学技术，包括循环伏安法和法拉第导纳研究。 此外，FTIR光谱将用于识别电极/溶液界面处的反应物和反应物中间体。 氧还原发生在每个燃料电池的阴极，甲醇氧化为二氧化碳和水是燃料电池研究的重要领域。 学生将在替代能源研究的这一重要领域接受培训。
