Surface reconstruction of pure-Cu single-crystal electrodes under CO-reduction potentials in alkaline solutions: A study by seriatim ECSTM-DEMS
Quasi-operando electrochemical scanning tunneling microscopy (ECSTM) recently showed
that a polycrystalline Cu electrode kept in 0.1 M KOH at− 0.9 V (SHE), a potential very close
to that for electrochemical CO reduction, underwent a two-step surface reconstruction,
initially to Cu (111), or Cu (pc)-[Cu (111)], and terminally to Cu (100), or Cu (pc)-[Cu (100)].
When subjected to monolayer-limited Cu (s)↔ Cu 2 O (s) oxidation-reduction cycles (ORC),
the Cu (pc)-[Cu (100)] surface was further transformed to Cu (pc)-[Cu (511)] that produced C …
