Practical Development of Electrochemical Sensors and Redox Flow Batteries Based on Nanostructured Design Strategy of Solid Electrode Surface

Abstract

This article reports a brief review of electrochemical sensors and redox flow batteries based on nanostructured design strategy of solid electrode surface developed by our team, and then the practical applications of proposed techniques are introduced. The first content consists of surface modification techniques of solid electrode materials such as metal and carbon, which can control electro-catalytic activity and application for the determination various electroactive species. The second topic describes electrochemical sensors based on the batch injection coulometry by using our presented electrodes, which exhibited absolute determination of inorganic compounds in practical fields. Finally, we tried to develop vanadium redox flow batteries with high current density by using the electrochemical modified carbon felt electrodes.
