(a) Schematics of the experimental setup for imbibition of aqueous electrolytes into nanoporous gold (NPG) under controlled electrode potential. WE, working electrode; RE, reference electrode; CE, counter electrode. (b) Scanning electron micrograph showing the microstructure of NPG. Scale bar, 100 nm. (c) Cyclic voltammogram of current density, j, versus potential, E, in 1 M KOH solution at the potential scan rate of 1 mV s−1. The reference electrode is Ag/AgCl in 3 M KCl.
