双极纳米电极阵列实现单个铂纳米颗粒上氢气析出反应的电致化学发光成像
Electrochemiluminescence Imaging Hydrogen Evolution Reaction on Single Platinum Nanoparticles Using a Bipolar Nanoelectrode Array
摘要
Abstract
A high-density(5.7×108 cm-2)nanoelectrode array with the electrode diameter of 200 nm and the interelectrode dis-tance of 450 nm were fabricated.The nanoelectrode array consisted of gold nanowires embedded in a porous anodic aluminum ox-ide(AAO)matrix,having regular nanoelectrode distribution and highly uniform nanoelectrode size.The gold nanoelectrode array was used as a closed bipolar nanoelectrode array combined with electrochemiluminescence(ECL)method to map the electrocatalytic activity of platinum nanoparticles toward hydrogen evolution reaction(HER)by modifying the catalysts on single nanoelectrodes.Results show that HER on single bipolar nanoelectrodes could be imaged with the sub-micrometer spatial resolution.The present approach offers a platform to image local electrochemical activity of electrocatalytic materials,energy materials and cellular pro-cesses with high spatial resolution.关键词
