制备载Pd的分子筛电极 ,以CO吸附为探针结合电化学原位FTIR反射光谱 ,首次发现限定在分子筛超笼中的纳米Pd微粒对CO的吸附具有增强红外吸收效应。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.国家自然科学基金资助项目!(2 99730 35
