中文摘要 | 本研究主要以極化曲線法及循環伏安法,探討在氯化鈉溶液中二氧化錫界面層對二氧化鉛析出氯氣電化學活性之影響。結果顯示,界面層燒結溫度愈高及燒結時間愈長,電極化學活性愈高,XRD結果証實在此條件下產生之β-PbO₂較α-PbO₂多。在酸性溶液中,PbO₂/SnO₂/Ti電極析氧之使用壽命測試顯示,1 mole %Ru修飾界面層可提昇電極之使用壽命。 |
英文摘要 | The effect of SnO₂ interfacial layer on the electrocatalytic activity of PbO₂ / SnO₂ / Ti electrode towards chlorine evolution has been studied in sodium chloride solutions by polarization and cyclic voltammetric measurements. The results show that the electrocatalytic activity increases when the sintering temperature and time of the interfacial layer is increased. X-ray diffraction studies reveal that the quantity of β–PbO₂ phase formation is more than that of α-PbO₂ phase under these conditions. The service life of PbO₂/SnO₂/Ti electrode towards oxygen evolution in acidic solution improves when the interfacial layer is doped with 1 mole % Ru. |
