This method is based on the shift of open circuit potential of Pt-based reversible hydrogen electrode. The detection system was verified with a system generating hydrogen under galvanostatic conditions. Then, it was applied to aqueous|1,2-dichloroethane interface where hydrogen is produced with decamethylferrocene as electron donor.Hydrogen potentiometric sensorHydrogen evolution reaction (HER)Liquid-liquidDecamethylferroceneScanning electrochemical microscopy (SECM)Reversible hydrogen electrode (RHE)text::journal::journal article::research article
