摘要
In this paper, two heterogeneous catalysis mechanisms are introduced, namely: Chemical Reaction Mode Cyclic Catalysis Mechanism—CRMM and Electron Orbital Deformation-Recovery Cyclic Catalysis Mechanism—EODRM (or Electron Cyclic Donate-Adopt catalysis Mechanism—ECDAM. A number of difficulties encountered by CRMM are listed. The author clearly points out that CRMM is not credible. This false theory has misled us for more than 100 years. About EODRM or ECDAM, the article also gives a brief description. The key point of EODRM or ECDAM is that catalysts do not participate in chemical reactions, and catalysis phenomena are physical rather than chemical phenomena. It’s completely different from CRMM. The theory contains three main points: 1) There is a demarcation between the catalyst and the poison;2) The active size of the catalyst or the poison size of the poison is closely related to the electronegative size of the catalyst or poison;3) The active size of catalyst is closely related to the chemical state. The selectivity of catalyst is related to energy level. Photocatalysis, electrocatalysis, laser catalysis and microwave catalysis are all physical phenomena. It has different energy levels. According to this theory, the author thinks that there are several problems worth studying in production and scientific research, such as: alumina in the Fe ammonia synthesis catalyst has a serious poison effect on the iron catalyst, resulting in three high situations in ammonia synthesis production (high temperature, high pressure, high energy consumption). The support materials of automotive exhaust purification catalyst have used Cordierite (2MgO-2Al2O3-5SiO2) ceramic honeycomb support, which has a serious poisoning effect on noble metal catalysts, a lot of noble metals are wasted, and so on. These problems have long been ignored by the catalytic academia;the author considers that this reason may be due to a misunderstanding or mistranslation on the term “catalysis” and “catalyst”.
