Silver Leakage from Ag/AgCl Reference Electrodes as a Potential Cause of Interference in the Electrocatalytic Hydrogen Evolution Reaction.

The electrocatalytic hydrogen evolution reaction (HER) is of considerable interest for the production of H2 from sustainable sources. Herein, we show that under conditions commonly employed in identifying new electrocatalysts for this reaction (using Ag/AgCl reference electrodes in 1 M H2SO4), silver ions can leak from the reference electrode into solution… CONTINUE READING
