电催化界面和反应的电化学阻抗谱研究:经典永不褪色
Electrochemical Impedance Spectroscopy for Electrocatalytic Interfaces and Reactions:Classics Never Die
摘要
Abstract
This review article recapitulates electrochemical impedance spectroscopy (EIS) studies in the field of electrocatalysis.The history of this specialized field,ranging from the beginning of the twentieth century to now,is outlined.We then chronicle milestones of the impedance theory.Special emphases are put on the Dolin-Ershler model,the prevailing model for analyzing adsorption impedance data.Afterwards,we narrow into a very specific and fundamental topic,the double-layer capacitance at platinum (Pt) single crystals.We discuss the challenges in experimentation and theoretical understanding thereof.We cast doubts into the validity of using the Dolin-Ershler model to obtain the double-layer capacitance in dilute solutions,in which case diffuse charge effects become important and the low-frequency part of double-layer capacitance is lost.We wish to see future progress in proving or disproving the recent theoretical prediction that Pt electrode possesses a non-monotonic surface charging relation and negative double-layer capacitances in the oxide formation region.关键词
