Silicate and niobosilicate MCM-41 were used as su ports for gold introduced by post synthesis impregnation or by co-precipitation during the synthesis. The latter sample (AuMCM-41) exhibited unique properties for the WGS reaction, as revealed by in situ FTIR and FTIR/MS OPERANDO techniques. AuMCM-41 is activated by CO through the formation of oxygen vacancies in volved in oxygen adsorption and activation for the further reaction. This behaviour is not characteristic for Pt/MCM-41 catalysts and appears only after the introduction of niobium into the mesoporous matrix (Pt/NbMCM-41).
