在液相中研究了第四周期过渡金属氧化物在异丙苯氧化中的多相催化作用。和均相催化氧化所得结果相对照,证明金属离子的催化氧化活性和选择性由元素的原子序数所决定,和其存在的状态无关。所得动力学参数值说明,反应系按络合—链锁反应机理进行,氧化物催化剂通过吸附分子氧(配位)主要起引发作用。 In the liquid phase, the heterogeneous catalysis of the transition metal oxide in cumene during the fourth cycle was studied. Compared with the results of homogeneous catalytic oxidation, the catalytic activity and selectivity of metal ions are proved to be determined by the atomic numbers of the elements, regardless of their state of existence. The obtained kinetic parameters show that the reaction proceeds according to the complexation-chain reaction mechanism, and the oxide catalyst mainly initiates the action by adsorbing the molecular oxygen (coordination).
