概要
- 論文の詳細を見る
Reduction of carbon dioxide at p-type GaP photocathodes was investigated in lithium carbonate electrolytes. The reduction occurs in competition with hydrogen evolution and its current efficiency is enhanced by dissolving crown ether such as 15-crown-5 in the electrolyte. It is proposed that a chemical reaction pathway is involved in which the reduction of carbon dioxide is initiated by cathodically deposited lithium with formation of the anion radical of carbon dioxide.
