Study on the Mechanism of Heterogeneous Catalysis (4)—Electron Cyclic Donate-Accept Catalysis Mechanism-ECDAM or Electron Orbital Deformation-Reversion Cyclic Catalysis Mechanism-EODRM

摘要

This paper has expounded the derivation of the Electron Cyclic Donate-Accept Catalysis Mechanism-ECDAM or Electron Orbital Deformation-Reversion Cyclic Catalysis Mechanism-EODRM and its three main arguments as well as three argument verifications. These three main arguments are: 1) There is a demarcation between catalysts and poisons, or promoters and poisons. 2) The relative activities of catalysts or poisons of poisons are closely related to the Electrical Negativity Values-ENV of catalysts or poison. 3) The activities or ENVs of catalysts are closely related to the chemical states of substance being added. The ECDAM or EODRM can also be extended to iron or metal base catalyst for selecting promoter, support and judging poison. It can also be extended to the study of the fire retardant of carbon materials. The author holds that the catalytic phenomenon should be physical phenomenon rather than chemical phenomenon or not completely chemical phenomenon at least.
