Abstract: Photoelectrochemical carbon dioxide reduction was carried out at a p-type Si(111) electrode modified with a viologen molecular layer and AuCl4^[2-] or PdCl4^[2-]. It was proven that the reduction reaction was mediated by viologen moiety and while CO2 reduction was dominant at the Si(111) electrode modified with PdCl4^[2-] in the potential region where viologen moiety was in the first reduced state, it became dominant at the electrode modified with AuCl4^[2-] when viologen moiety became the second reduced state. FT-IR measurement confirmed the formation of formic acid/formate ion at the PdCl4^[2-]/viologen-modified Si electrode.
