a Electrocatalysis via direct electron transfer; (b) formate produced by electrocatalysis via direct electron transfer; (c) electrocatalysis via mediated electron transfer by adding 0.2 mM MV into the electrolyte; (d) formate produced by electrocatalysis via mediated electron transfer. Electrolyte: 0.1 M HEPES/NaOH, 0.1 M NaCl buffer, pH 7.0. A constant voltage of − 500 mV vs. SHE was used. The error bars correspond to the standard deviation of at least three independent measurements, and the center value for the error bars is the average of the three independent measurements. Source data are provided as a Source Data file.
