Structure of the (Bi)carbonate Adlayer on Cu(100) Electrodes

(Bi)carbonate adsorption on Cu(100) in 0.1 M KHCO(3) has been studied by in situ scanning tunneling microscopy. Coexistence of different ordered adlayer phases with ([Formula: see text] ×6 [Formula: see text] )R45° and (4×4) unit cells was observed in the double layer potential regime. The adlayer i...

description (Bi)carbonate adsorption on Cu(100) in 0.1 M KHCO(3) has been studied by in situ scanning tunneling microscopy. Coexistence of different ordered adlayer phases with ([Formula: see text] ×6 [Formula: see text] )R45° and (4×4) unit cells was observed in the double layer potential regime. The adlayer is rather dynamic and undergoes a reversible order‐disorder phase transition at 0 V vs. the reversible hydrogen electrode. Density functional calculations indicate that the adlayer consists of coadsorbed carbonate and water molecules and is strongly stabilized by liquid water in the adjacent electrolyte.
