• 中文摘要： 利用循環伏安、定電位及動態電位技術,可以了解熱分解所製備之釕-鈀-錫氧化物電極在0.5莫耳/升硫酸液中的氧氣發生之電化學觸媒活性與披覆溶液中鈀添加量的關係。除了添加10莫耳百分比的鈀之外,其餘之氧化物都因為鈀的添加使得電極有較明顯的氧化還原峰和較大的背景電流而獲得較大的活性。掃描式電子顯微鏡所得之電極表面狀也提供了如上的解釋。不過,氧化物的單位活性(電流/電荷)則在鈀的添加量超過30莫耳百分比時,才會大於釕錫雙成分氧化物的單位活性。塔弗曲線的結果也獲得了與前述一致的結論。
• 英文摘要： The electrocatalytic activity of Ru, Sn, and Pd mixed oxides by thermal decomposition for oxygen evolution from 0.5mol dm/sup -3/ H/sub 2/SO/sub 4/ solution has been studied as a function of Pd content in the coating solution through means of cyclic voltammetry, potentiostatic, and potentiodynamic techniques. The addition of Pd in coating solutions rendered the electrodes (with the exception of 10 mol% Pd) which earned a higher voltammetric, charge coming from higher redox peaks and higher background currents with increasing Pd content. SEM morphologies were also investigated to provide an explanation for this phenomenon. The addition of Pd has been indicated by the specific activity (i/q/sup */) to not increase the specific activity of this ternary oxide until the amount of Pd is in excess of 30 mol%. The Tafel-lines study has also provided the similar conclusion as q/sup */ and i/q/sup */.
