论文摘要
提出了动力学理论，以阐明表面上吸附和解吸的复杂性质，并以一种简单的方式计算吸附和解吸速率。该理论提供了能量障碍的分解，并考虑了吸附物之间横向相互作用的协同作用。得出了一种简洁的公式，以吸附和吸附速率，上面覆盖有多组分吸附物。吸附率和解吸速率是通过分别与经典理论的两体协同系数相比，分别依赖于表面覆盖的两体协同系数来提出的。
A kinetic theory is proposed to elucidate complex nature of adsorption and desorption on surface and to calculate the adsorption and desorption rates in a practically simple way. This theory provides decomposition of the energy barriers and considers synergistic effects of lateral interactions between adsorbates. A concise formulation was derived for adsorption and desorption rates on surfaces covered with multi-component adsorbates. The adsorption and desorption rates are formulated by multiplying a two-body synergistic coefficient that is explicitly dependent on surface coverage, compared respectively to those from classical theories.
