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.
已经比较了钨、碳化钨和铂表面区域的局部电子结构。与碳化钨具有类铂催化活性是由于碳原子价电子对钨的 5d 带贡献的假设相反，从钨到碳化钨，d 带未填充部分的宽度增加。
