【摘要】 本文对氢、氧在过渡金属上的反应活化能以经验的键能键级（BEBO）进行预报。就表面反应的Rideal-Eley历程而言,将催化特性彼此不同的24种过渡金属分为四类:A、B、C和D。这24种金属的每一个,其表面反应的Langmuir-Hinshelwood历程活化能或反应势能皆比Rideal-Eley历程为高。在本文中,所采用的方法和实验获得的数据之间做了有利地比较;对“低化学吸附-高催化活性”这一局部催化氧化反应适用规则做了进一步地讨论。更多还原

【Abstract】 The empirical bond energy bond order (BEBO) approach has been extended in order to make predications of the energies of activation of reactions for H2 and O2 on transition d-metals. Thus, for the Rideal-Eley mechanism of the surface reaction the 24 d-metals with different catalytic properties are predicated to be approximately classified into four groups A, B, C and D. In accordance with Langmuir-Hinshelwood mechanism, the surface reaction for each of the 24 d-metals has higher energy of activation or reaction potential energy than these from the Rideal-Eley mechanism reasoning.In this paper, favourable comparisons are made between the results of this approach and available experimental data. The "low chemisorption heats -high catalytic activities" rule for some catalytic oxidation reactions has been fully discussed.更多还原
