摘要：
In situ fourier transform-infrared reflection absorption spectroscopy reveals the formation of a formate intermediate during the CO hydrogenation reaction at high pressures over a potassium promoted Ru(001) surface. The vibrational data indicate bond formation between potassium and formate. The present results suggest a dual function of alkali promoters in this reaction - promotion of CO bond dissociation and direct participation in the formation of reaction intermediates.
