Abstract:

Platinum group metals possess high stability and activity in electrocatalysis and are frequently used in fuel cells^[1].However, their commercial applications are limited owing to the high cost. Accordingly, one of the most important subjects of electrocatalysis is to select suitable substrate materials to disperse platinum group metal and prepare electrocatalysts of high performance and low cost. In this paper, nanoparticles of palladium (Pd₁₃) were synthesized in supercages of Y-zeolite according to the procedure of literature^[2] The electrode of palladium-loading zeolite film supported on Pt substrate (Pd⁰Y/Pt) was characterized by cyclic voltammetry, and the adsorption of carbon monoxide on the electrode was studied using in situ electrochemical FTIR reflection spectroscopy.
