Dispersibility of w species on the surface of w tio2 catalysts 2催化剂表面上钨的分散性
The dispersion of mo species on the surface of al - clm and - al2o 3催化剂表面上钼的分散性
This phenomenon was closely related to the transportation and extraction rate of carbon atoms in the surface of catalysts at different temperatures 这种现象与不同温度下碳原子在催化剂表面的迁移和析出速率密切相关,也即与不同温度下催化剂的活性有关。
Because the tungsten from the phosphotungstic acid could pull out and deposit on the surface of catalyst , and the electronegativity of mo - o is smaller than that of w - o . the smaller the electronegativity is , the higher oxidation activity is . thus phosphomolybdic acid shows better catalytic oxidation activity than phosphotungstic acid 由于磷钨酸中的钨可以脱出并少量沉积到催化剂表面,而且从电负性来说mo - o的键能小于w - o ,键能小的杂多酸有较强的氧化性,所以钼系杂多酸催化活性要好于钨系杂多酸。
