Surface Electronic Properties of Tungsten, Tungsten Carbide, and Platinum
J E Houston ; G E Laramore ; Robert L Park ;
Date 19 Jul 1974
Journal Science, 185 (4147), 258-260
AbstractThe local electronic structures of the surface regions of tungsten, tungsten carbide, and platinum have been compared. Contrary to the hypothesis that the platinum-like catalytic activity of tungsten carbide results from the contribution of carbon valence electrons to the 5d band of tungsten, the width of the unfilled portion of the d band increases on going from tungsten to tungsten carbide.
