Work Focused on Hydroxyl Radical Published on ES&T

Yin Jing’s recent research on ‘Mechanistic Study of the Validity of Using Hydroxyl Radical Probes To Characterize Electrochemical Advanced Oxidation Processes‘ has been published on Environmental Science & Technology.

The goal of this research is to justify an appropriate probe for hydroxyl radical detection used in the electrochemical advanced oxidation processes (EAOPs). The motivation came from an unexpected result when coumarin was used as the probe to detect hydroxyl radical produced on a substoichiometric TiO2 electrode. An extensive literature review has revealed that many paper used the wrong probes in the electrochemical systems, including EAOPs, battery and photocatalysis.
