| Abstract: | Adsorption of CO on palladium loading zeolite el ectrode supported on Pt or GC substrate was studied by in situ MSFTIR spectrosco py.The results demonstrated that the geometry of faujasite supercages favors the formation of bridge-bonded CO species.The enhanced IR adsorption of CO adsorbe d on Pd clusters located in the supercages of zeolite has been observed for the first time,which is a new phenomenon and differs from the abnormal infrared effe cts discovered by our group and the surface enhanced infrared absorption phenome non reported in the literature. |
