基于对Ru/Pt薄膜和商用Johnson-Matthey PtRu/C上甲醇氧化反应（MOR）的原位衰减全反射-表面增强红外反射吸收光谱（ATR-SEIRAS）的详细研究，提出了一种修正的MOR增强机制，其中Pt位点上的CO无关，而是Pt-Ru边界位点催化氧插入反应，导致甲酸的形成，并增强了直接反应途径。
Based on detailed insitu attenuated total-reflection-surface-enhanced IR reflection absorption spectroscopy (ATR-SEIRAS) studies of the methanol oxidation reaction (MOR) on Ru/Pt thin film and commercial Johnson-Matthey PtRu/C, a revised MOR enhancement mechanism is proposed in which CO on Pt sites is irrelevant but instead Pt-Ru boundary sites catalyze the oxygen insertion reaction that leads to the formation of formate and enhances the direct reaction pathway.
