초록

전해질에 존재하는 NaCl이 Ti/IrO2 양극에서만 페놀 산화에 대한 촉매의 활성을 보이고 Ti/SnO2의 양극에서는 촉매의 활성을 보이지 않았다. NaCl 촉매의 작용은 전해질 내부 또는 양극 근처에서 전기분해로 생성된 ClO(-)가 유기물의 산화에 관여하는 것으로 기인함.

The activity of catalyst for oxidation of phenol, in the presence of NaCl electrolyte, has shown only at the Ti/IrO2 anode and not at the Ti/SnO2 anode. The catalytic action of NaCl was attributed to the participation of electrogenerated ClO(-) in the oxidation of organics, phenol and its oxidation products, near the anode or/and in the electrolyte.

Keywords:catalyst;electrolyte;phenol
