基于易位吸附模型推导出了化学吸附和交换动力学的解析表达式,这些动力学方程可从理论上剖析强化学吸附分子的压强促进脱附速度与其吸附过程之间的关系。本工作完满解释YCO/CO*在Pd(111)和Rh多晶表面上的气相-表面交换动力学特征,并强调指出在实验温度和气相压强范围内CO在Pd表面上强弱吸附态的动力学性质差别明显。文中还对易位吸附模型和化学吸附的前驱态理论之间的一致性进行了探讨。
Based on the metathesis adsorption model, analytical expressions of chemisorption and exchange kinetics are deduced. These kinetic equations can theoretically analyze the relationship between the rate of desorption and the adsorption process by the pressure of strong chemisorption molecules. This work fully explains the gas-surface exchange kinetics of YCO / CO * on the Pd (111) and Rh polycrystalline surfaces and highlights the dynamics of CO adsorption on the Pd surface in the experimental temperature and gas pressure ranges Significant differences in the nature of learning. The paper also discusses the consistency between the adsorption model of metathesis and the precursor theory of chemisorption.
