Controlled Synthesis of Pd Nanocube-Polyaniline Hybrids for Ethanol Oxidation Reaction

摘要

Palladium (Pd) nanocrystals (NCs) have been extensively studied due to their unique and distinct properties in myriad important applications.1-3 Among the various shapes of NCs, Pd nanocubes have attracted enormous interest as electrocatalysts compared with Pd NCs enclosed of low-index facets such as octahedral and spherical NCs.4-6 However, significant challenges still remain for satisfactory electrocatalytic activity and stability when shape-controlled Pd NCs are employed as catalysts in various electrocatalytic reactions. To overcome the limitations of Pd NCs in electrocatalytic reactions, incorporation of a conductive polymer into Pd NCs is one of the effective strategies recently explored in various electrocatalytic applications.7'8
