摘要

To date,due to the excellent electrochemical inertness,superb electrical conductivity and good mechanical stability in both aqueous and nonaqueous solutions,platinum (Pt) has been widely employed as counter electrode material in three-electrode setups to perform electroanalytical chemistry.However,recent reports have revealed that the use of Pt based counter electrodes for hydrogen evolution reaction (HER),without using any ionexchange membrane to separate the working electrode from the counter electrode,would influence the experimental results substantially owing to the electrochemical dissolution-deposition process of Pt.A controversial issue has therefore arisen regarding whether or not Pt should be continued to be utilized as the counter electrode material for HER.
