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 electrodesTo date, due to the excellent electrochemical inertness, superb electrical conductivity and good mechanical stability in both aque- ous 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 ion- exchange membrane to separate the working electrode from the counter electrode, would influence the experimental results sub- stantially owing to the electrochemical dissolution-deposition pro- cess 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.
