但是,他们的反应机理有所不同。 未催化的反应通过一步式机理进行 (仅观察到一个过渡状态)。 相比之下,催化反应遵循两步机理 (观察到两个过渡状态) ,激活能量明显较少。 反应途径的这一差异说明了催化剂在提供具有较低启动能量的替代反应机理方面的作用,从而加速反应。
催化剂的分类可以是均相催化剂(Homogeneous Catalyst)也可以是异相催化剂(Heterogeneous catalysis),绝大部分的催化过程都是在异相催化剂的作用下完成顾名思义,异相催化剂就是反应物和催化剂在不同相中,往往以固体催化剂,流体的反应物作为体系成对出现。 两个典型的图像: Figure 3: Homogeneous catalysis Figure 4:...

Catalysis - Enzymes, Heterogeneous, Homogeneous: Catalysts may be classified generally according to their physical state, their chemical nature, or the nature of the reactions that they catalyze. Catalysts may be gases, liquids, or solids. In homogeneou

Homogeneous catalysis is a type of catalysis in which the catalyst operates in the same phase as the reactants — usually dissolved in a solvent. Mechanistic studies of homogeneous catalysts are generally easier than those of heterogeneous catalysts, which aids optimization. They can, however, be ...
