Abstract
Palladium-based electrocatalysts have become an important research field in energy generation. Introducing another metal element in palladium-based catalysts may improve the electrocatalytic performance while reducing costs. In this work, colloidal nanocrystal assembly (CNA) of Pd3Pb alloy has been synthesized via an aqueous-solution synthesis method. The content of Pb in Pd3Pb CNAs can be adjusted to obtain an optimal value with the highest catalytic current density of 3543 mA/mgPd. Meantime, the morphology of the Pd3Pb catalysts was found to form the well-separated spherical structures with the size range from 120 nm to 140 nm. The variation of the molar ratio of elements Pd and Pb in Pd3Pb CNAs leads to form mainly spherical assemblies with a minor part of nanoparticles. Combined the XRD, TEM and electrochemical results, the high catalytic performance towards electrooxidation of ethanol for Pd3Pb CNAs was suggested to be ascribed to the nature of small crystallite sizes and the assembly structure along with the formation of bimetallic alloy.
