Abstract
Description
酸化反応:2H2O→O2+4H++4e− (1)
還元反応:CO2+2H++2e−→HCOOH (2)
:2H++2e−→H2 (3)
<酸化反応用電極の作製>
1mMの塩化イリジウム酸(IV)カリウム(K2IrCl6)水溶液25mlと1mMの塩化ルテニウム(RuCl3)水溶液25mlとの混合溶液に、10wt%の水酸化ナトリウム(NaOH)水溶液を加えて、pH13に調整した溶液を得た。当該溶液を氷水で1時間冷却した後、3M硝酸(HNO3)水溶液を滴下してpH1に調整し、酸化イリジウム(IrOx)/酸化ルテニウム(RuOx)のナノコロイド水溶液を得た。この溶液に1.5wt%NaOH水溶液を滴下してpH12に調整した。
Ti製基板を、フッ素含有酸化錫(FTO)を被覆したガラス基板に代えたこと以外は、実施例と同様に酸化反応用電極を作製した。
Claims (3)
