“…atomic steps, edges, and kinks, the surface conditions of the catalysts are of vital importance for the catalytic efficiency [7,12,16]. The electrocatalytic activity of the gold nanoparticles can be significantly decreased by adsorbed organic layers [1,11,13]. Thus, much research has been devoted to clean the surface, hence improving the electrocatalytic activity of the Au NPs [12,13,16,19].…”
