Abstract
Description
図1は、実施の形態に係る電気化学還元装置10の概略構成を示す模式図である。図2は、実施の形態に係る電気化学還元装置10が有する電極ユニットの概略構成を示す分解斜視図である。図3は、実施の形態に係る電気化学還元装置10が有する電極ユニットの概略構成を示す側面図である。
<酸素発生用電極での電極反応>
3H2O→1.5O2+6H++6e−:E0=1.23V
<還元電極での電極反応>
トルエン+6H++6e−→メチルシクロヘキサン:E0=0.153V(vs RHE)
すなわち、酸素発生用電極での電極反応と、還元電極での電極反応とが並行して進行し、酸素発生用電極130での電極反応によって、水の電気分解により生じたプロトンが電解質膜110を介して還元電極120に供給される。還元電極120に供給されたプロトンは、還元電極120での電極反応において、芳香族化合物の核水素化に利用される。
