a CE at 0.7 VRHE with different times, (b) PE3 after CE at 0.7 VRHE with different times and (c) different PE protocols (PE1 − PE5: EH = 0.7 VRHE for 0.05 s, EL = 0.3 VRHE for 2.0, 1.0, 0.5, 0.2 and 0.05 s, respectively). d Adsorption energy of GLY, C2H5O2CH(OH)2 (transformed from GLAD), and GLA on Pt (111) in an alkaline electrolyte. The three inset images present the optimized adsorption geometry of the corresponding three species on the Pt (111) surface. The color for each element is tangerine yellow for H, light blue for O, purple for C, and gray for Pt, respectively.
