چکیده انگلیسی
The activity and selectivity are dependent on the catalyst and if they are structure sensitive, they depend strongly on the surface active sites, suffering transformations during the reaction, which have to be taken in account. FTIR and ISS measurements in situ explain the interface metal oxide site formation during CO oxidation and methane reforming and XPS data the structure transformation at the surface after different pre-treatment and propane oxidation. It was observed that in reducible oxide supports the oxygen is responsible for the surface interaction between different structures, affecting strongly the reaction rate.
