Trimetallic Pd@SnZr/ZSM-5 as an Efficient Electrocatalyst for Glucose Electrooxidation in Alkaline Media

The depletion of fossil fuels and environmental problems have increased interest in renewable energy systems. In this context, fuel cells are a promising technology for sustainable energy production. In this study, a ZSM-5-supported trimetallic Pd@SnZr/ZSM-5 catalyst was synthesized for glucose electrooxidation in an alkaline environment, and its electrochemical performance was investigated. Catalysts were prepared at different Pd loading rates, and their structural properties were characterized by XRD, SEM-EDS, and temperature programmed analysis. The results showed that the ZSM-5 structure was preserved and Pd, Sn, and Zr species were successfully dispersed. In electrochemical measurements, the catalyst with 5% Pd loading showed the highest activity, reaching a current density of 0.371 mA/cm2 and exhibiting low charge transfer resistance. The findings reveal that the Pd@SnZr/ZSM-5 catalyst is a promising anode material for glucose fuel cells.
