This article reports a study of electrochemical cycling effects on hydrogen evolution catalytic activity of gold nanoparticles in sulfuric acid. We found that after cycling within the double layer regime, up to 0.64 V vs RHE, there is a dramatic effect on the HER activity of gold nanoparticles: 128...
