摘要：
The propylene oxidation reaction has been studied using O-18(2) on well defined MoO3 crystallites. Results show that the information of products -acrolein and carbon dioxide- involves the lattice oxygen. The different O-18-labelling, according to selective or total oxidation products, agrees with the structure sensitivity of this reaction. Post reaction analysis (by LRS, SIMS, LEIS) support a redox equilibrium which determines the O-18 concentration in the surface layers.
