摘要: 本文通过对LaNi_5活化过程动力学的研究,论证了LaNi_5的清洁表面具有使氢分子分解为氢原子的催化作用。这种催化作用因氧在表面的存在而丧失,活化过程就是清除氧的污染而形成清洁表面的过程。孕育期的存在是表面污染引起的,已活化的LaNi_5中未释放的氢可减轻氧对LaNi_5表面活性的影响。
Abstract:A discussion on the catalytic action of clean surface of LaNi_5, by which the molecular hydrogen disassociated into atoms, is presented according to the study of the activation process kinetics of LaNi_5. It was confirmed that the catalytic action will be poisoned by oxygen on its surface. The activation process is removal of the pollution by oxygen and thereby forms a clean surface. How the incubation period come into existence is due to the surface pollution. The unreleased hydrogen stored in activated LaNi_5 can relieve the influence of oxygen upon the surface activity of it.
