Controlling the Synthesis Protocols of Palladium‐Based Nanostructures for Enhanced Electrocatalytic Oxidation of Carbon Monoxide: A Mini‐Review

Pd‐based nanostructures are endowed with impressive catalytic features for alcohol‐based fuel cells, however, their poisoning by carbon monoxide (CO) is a great barrier to large‐scale utilization of such fuel cells as alternative power sources. The need to optimize the electrochemical CO oxidation (CO_Oxid) of Pd‐based nanostructures in various electrolytes has attracted much attention in the last decade, so it is important to provide a timely update on this area of research. This mini‐review highlights the most recent advances in controlling some synthesis methods of Pd‐based nanostructures and their morphologies for enhanced electrocatalytic CO_Oxid in different electrolyte conditions in the last three years. Finally, the main challenges for commercially viable Pd‐based nanostructures for electrochemical CO_Oxid are discussed, highlighting the future perspectives and providing promising solutions for practical CO_Oxid application.
