Preparation, Characterization and Electrochemical Behavior of Pd‐Au Alloy Incorporated into Zeolites/Graphite Electrodes

Abstract

The present article reports the preparation of Pd‐Au alloy incorporated into NaY zeolites layer via simple immersion technique. Pd‐Au particles were incorporated into zeolites cages via Co‐impregnation or alternate impregnation of metal ions. Cyclic voltammetry was used to evaluate the state of the modified electrodes in alkaline media. Surface morphology as well as elemental composition of the modified layer were examined using Scanning electron microscopy (SEM) and energy dispersive X‐ray (EDX).

“…Moreover, zeolites can be used as support for more than one metal, then simulating bimetallic alloys. So, El-Shafei et al [12] incorporated Pd and Au into graphite/zeolites electrodes and the sequence of immersion as well as the concentration of metal ions determining the alloy composition. The acidity and pore diameter of the zeolites must also be considered for each particular application [13].…”
