Au Nanowires@Pd-Polyethylenimine Nanohybrids as Highly Active and Methanol-Tolerant Electrocatalysts toward Oxygen Reduction Reaction in Alkaline Media

Optimizing the shape, structure, and interface of noble metal bimetallic nanostructures significantly improves their catalytic properties. Recently, Au@Pd core–shell bimetallic nanostructures have attracted considerable interest for fuel cell applications. Regrettably, most of the research mainly focuses on the morphological and structural control whereas interfacial control is neglected. In this work, polyethylenimine (PEI) functionalized Au...
