Bipyridine derivatives were covalently anchored on the surface of the mesopores of MCM-41 porous material and the further introduction of Ag+ions led to the formation of Ag+ bipyridine complexes by the chelation of the Ag+ions with the bipyridine units. The successful covalent immobilization of the bipyridine derivatives as well as the Ag+ bipyridine complexes has been confirmed by various spectroscopic investigations such as FT-IR, UV-vis, and XPS analyses. It was found that the anchored bipyridine derivatives on the surface of MCM-41 prevent the reduction and agglomeration of the Ag+species even after evacuation treatment at 573 K. Thus, the anchored Ag+ ions chelated with the bipyridine units inside the mesopores of MCM-41 were observed to exhibit photocatalytic reactivity for N2O reduction with CO.
