文中归纳了氧化物禁带宽度与其电子结构、当量生成热和金属离子半径间的关系,闡明了当量生成热和金属离子半径这两个参数有明确的物理意义,与氧鍵能、金属性和原子间距有关,与氧化物的催化性质也有关。根据氧化、裂化等多种催化性质与禁带宽度的关系,指出了稀土氧化物由于有不同的禁带宽度,所以有不同的催化性质。
The relation between the forbidden band width of oxide and its electronic structure, the equivalent heat of formation and the radius of metal ion are summarized in the paper. The two parameters of equivalent heat of formation and metal ion radius have clear physical meaning, which are in agreement with oxygen bond energy, Atomic distance is related to the catalytic nature of the oxide. According to the relationship between the catalytic properties such as oxidation and cracking and the forbidden band width, it is pointed out that the rare earth oxides have different catalysis properties because of their different forbidden band widths.
