金属态原子电负性的计算及应用(II)
English
Calculation of Solid Metal Atom's Electronegativity and its Application(II)
Abstract:
In this paper, heat of chemisorption and surface bond energies of diatomic molecules (H2, O2, CO) on some transition metals surface are empirically calculated based on the modified Pauling's equation, i.e.,
EM-A,S=(αEM-M+EA-A,S)/2+23(X-βXA)2
where XM is a newly defined electronegativity of solid matal atom by the author. These surface bond energies will be useful for understanding the nature of catalytic surface reaction.
