Insights into Electrochemical Dehalogenation by Non-Noble Metal Single-Atom Cobalt with High Efficiency and Low Energy Consumption

Single-Atom Iron Can Steer Atomic Hydrogen toward Selective Reductive Dechlorination: Implications for Remediation of Chlorinated Solvents-Impacted Groundwater

“…Quenching tests with TBA verified the significant contribution of H* to TCE dechlorination by Fe 0 @Fe-N 4 -C. TBA is recognized as an effective quencher for H* and • OH. ,, Under the anaerobic conditions of this study, no • OH (Figure a) or other reactive oxygen species (e.g., O 2 •– and 1 O 2 ) were generated (Figure S21), while H* was detected during TCE dechlorination test (Figure S22). Therefore, the addition of TBA will only affect H* in the reaction system.…”
