Abstract
The 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 5 d band of tungsten, the width of the unfilled portion of the d band increases on going from tungsten to tungsten carbide.Keywords
