19 Jul 1974 | Journal: | Science, 185 (4147), 258-260 | 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 5d band of tungsten, the width of the unfilled portion of the d band increases on going from tungsten to tungsten carbide. | Source: | PubMed, pmid17812052 doi: 10.1126/science.185.4147.258 | Services: | Forum | Review | Favorites |
