a Quenching of reaction with the addition of TEMPO radical scavenger. All error bars represent standard deviation based on three independent samples. b EPR spectra of the anolyte with and without NO3-, using TEMPO to track the formation of radical intermediates. c UV-vis spectra of the anolyte before and after reaction. d Half-cell potential and Faradaic efficiency of benzaldehyde over 100 h. e Composition of the CoOx/IrO2 anode before and after 100 h of reaction, based on EDX analysis. Source data for Fig. 2a-e are provided as a Source Data file.
