摘要

The results on the equilibrium pressure measurement of BaCO3 + C = BaO + 2CO reaction and the demonstration of chemical state of iron proved that decomposition-generation cycle of BaCO3 and oxidation-reduction cycle of Fe in that reaction condition case were impossible to occur. The Chemical Reaction Model Catalytic Cycle Mechanism-CRMM does not exist at all for BaCO3, Fe, Noble metal catalysts. To call CRMM as a “principle” was obviously inappropriate. The TOF (Turnover Frequency—TOF: unit: s-1) was used to measure the activity size and life of catalyst, and it is clearly out of nothing.
