Single-atom catalysts (SACs) have attracted considerable interest for their potential to improve the efficiency of chemical reactions. Here, we report the synthesis and characterization of a Pd/CeO2 SAC for the oxygen reduction reaction (ORR). CeO2 nanocubes as the catalyst support were successfully synthesized and characterized by XRD and TEM. Single atoms (Pd1) were loaded on the nanocubes to create the SAC. It is expected that the Pd/CeO2 SAC would show improved ORR activity compared to the Pd nano-crystalline catalyst, highlighting the potential of SACs for improving catalytic performance. Additionally, this work could pave the way for the extension of this method to other metals and supports, leading to a better understanding of how catalysts can be designed to maximize the ORR performance.
