摘要

The electrochemical oxidation and infrared spectral features for carbon monoxide adsorbed on Pt(100) and Pt(110) in 0.1 M NaOH were studied as a function of the annealing/cooling treatment with the objective to establish the influence of the platinum surface site geometry and the role of surface order in the electro-oxidation of CO on these two surfaces. Two common cooling methods (Ar and H2/Ar atmospheres) were employed for both surface electrodes. Additionally, CO cooling and I2 vapour cooling methods were used for Pt(100) and Pt(110), respectively. Multiple CO vibration bands were observed on both electrode surfaces, their distribution and potential dependence strongly depending on the surface treatment.
