Enhancement of IR absorption of CO adsorbed on palladium-loading zeolite thin film electrode

In the present paper, clusters or nanoparticles of palladium were synthesized by using ship-in-a-bottle technology in supercages of Y-zeolite. In situ electrochemical FTIR reflection spectroscopy was employed to study CO adsorption on nanoparticles of Pd in supercages of Y-zeolte. A novel phenomenon of enhancement of IR absorption of adsorbed CO was revealed for the first time. In comparison with IR absorption of CO adsorbed on a massive palladium electrode, IR absorption of CO adsorbed on nanoparticles of Pd has been enhanced up to about 40 times. The results also demonstrated that the new phenomenon of enhancement of IR absorption is related to the nanometer scale of Pd clusters and also to the particular environment of supercages of Y-zeolite.
