General Synthesis of Pd-pm (pm=Ga, In, Sn, Pb, Bi) Alloy Nanosheet Assemblies for Advanced Electrocatalysis
Owing to the synergistic compositional and structural advantages, the ultrathin bimetallic nanosheet assemblies nanostructures are thus widely recognized as advanced catalysts for alcohol electrooxidation reaction. Although vast efforts have been made, the fabrication of well-defined ultrathin bimetallic nanosheet assemblies (NSAs) at large scale is still a tough challenge. Herein, a universal synthetic approach has been proposed to produce a series of well-defined Pd-pm (pm= Ga, In, Sn, Pb, Bi) alloy NSAs. Due to the multiple merits of unique 3D flower-like nanostructure and alloyed crystalline features, the self-supported Pd-pm NSAs show excellent electrocatalytic performance for methanol oxidation reaction (MOR) and glycerol oxidation reaction (GOR). Given the eco-friendly synthetic concept, facile universality, and outstanding electrocatalytic properties of generated bimetallic Pd-pm NSAs, we believe that this method could be employed for building more advanced nanocatalysts toward efficient electrocatalytic application.
