安定化ジルコニア電気化学セルを用いたベンゼンガスの分解

抄録

It was tried to decompose benzene gas electrochemically by using electrochemical cell in the temperature range between 250 and 400°C, where 8 mol% Y₂O₃ doped ZrO₂ (YSZ) well known as oxide-ion conductor was used for the electrolyte of electrochemical cell. Benzene gas was decomposed quantitatively to CO₂ and H₂O without any byproduct. The amounts of decomposed benzene increased with increasing the cell temperature or applied voltage (0-10 V) respectively, independent on the benzene concentration. The current increased with proportion to the square value of applied voltage.
