【摘要】 离子转移(IT)与电子转移(ET)反应以及两者的偶合过程普遍存在于生命体系和能量转化过程中。本报告主要介绍不同和相同材质的微/纳米杂化或同质电极的制备方法、电极的表征及其它们在分析化学中的应用举例。采用所制备的电极可用来研究液/液界面上复杂的离子转移与电子转移以及可能的偶合反应;同时也探讨界面上分子电催化所涉及的质子偶合的电子转移反应(Proton-Coupled Electron Transfer,PCET)的机理;发展可同时检测离子电流和氧化还原反应电流的微/纳米电化学传感器。更多还原

【Abstract】 Electron transfer(ET), ion transfer(IT) and their coupling processes are common phenomena in life systems and energy conversion processes. In this presentation, we will mainly introduce how to fabricate dual glass microelectrode and hybrid microelectrode, characterization of these electrodes and their applications in Analytical Chemistry. These fabricated electrodes have been employed to study the ET, IT and possible their coupling reactions at a Liquid/Liquid interface; the mechanisms of proton coupled electron transfer(PCET) reactions, and develop novel dual function micro and nano electrochemical sensors.更多还原
