Abstract:

Exploring new oxygen electrocatalysts for oxygen reduction and evolution reactions (ORR and OER) has been one of hottest topics in recent years. This tutorial presentation will introduce recommended practices for measuring the oxygen electrocatalysts. The objective of this presentation is to help new students and learners to master the basic knowledge and lab skills for reliable electrochemical measurements. Some simple demonstration will be given along with the introduction. The skills to be introduced includes 1) electrode preparation, 2) electrochemical cell set-up preparation, 3) potential conversion principles, 4) measurement practices for ORR and OER, 5) data analysis, 6) mass-transport correction, 7) iR-drop correction, 8) capacitance correction, 9) data storage and documentation, and 10) some details need attention during the measurement.
