Description
Summary:Understanding the electrocatalytic activity at single nanoparticles/nanoclusters level is extremely important. In this work, a method for the electro‐deposition of single Pt–Pd nanoparticles (NPs) is described using a single nanopore electrode as a template. The electro‐deposition process was investigated carefully and the results show that the process is controlled by diffusion and electro‐crystallization process, simultaneously, and the glass sheath property around the nanopore has a large impact on the formation of single Pt–Pd NPs due to the “edge effect”. The prepared single Pt–Pd NPs exhibit excellent electrocatalytic activity in the methanol oxidation reaction, which can be used to screen electrocatalysts with high efficiency for utility in the energy field. Living on the edge: Single Pt–Pd nanoparticle (NPs) electrode was fabricated by an electro‐deposition method using a single nanopore electrode as a template, which was controlled by the “edge effect.” The prepared single Pt–Pd NPs exhibit excellent electrocatalytic activity towards methanol oxidation reaction, which can be used to screen electrocatalysts with high efficiency for utility in the energy field.
