本篇研究是基於先前對於二氧化鈦被覆於碳鋼之抗蝕能力研究，加以製備了摻雜鉑金的二氧化鈦塗層，以此提升其光觸媒能力。分別探討了不同比例的鉑金摻雜量以及不同鍛燒條件下二氧化鈦被覆於導電玻璃 ITO 與碳鋼上呈現的抗腐蝕能力，並探討紫外光與日光照射下光觸媒能力的變化。二氧化鈦被覆層可以應於玻璃與金屬表層上，其光觸媒能力可使被覆玻璃後可使其達到自我清潔，而金屬上能提升抗腐蝕能力；由於出發條件要有紫外光波段，預期摻雜鉑金於二氧化鈦塗層內能更加提升光催化能力，使日光(含紫外光波段)照射下能發揮更好效果。此研究使用的被覆基材為導電玻璃 ITO 與碳鋼金屬，二氧化鈦被覆於玻璃上時，利用導電層 ITO 的存在可以測試被覆層能否發
揮功效；被覆於碳鋼上可降低環境造成的腐蝕速率。二氧化鈦被覆於碳鋼時，發現鐵離子會因鍛燒過程而擴散進入二氧化鈦塗層，降低光催化能力，此問題與先前研究一致。因此本實驗參照先前研究結果，將碳鋼進行600OC預氧化，以氧化層作隔絕，來降低基材中鐵原子擴散問題。接著二氧化鈦被覆層經過不同鍛燒溫度後，再紫外光(UV)照射下，發現400OC熱處理皆在被覆於碳鋼與 ITO上有較佳的光催化能力，ITO 上能達到約 500mV 電位變化；而碳鋼有170mV 電位變化，且能將腐蝕電流密度從 2.22×10-6降低至 1.19×10-9，有 3 個數量級。摻雜鉑金後，在最多摻雜量下二氧化鈦鍛燒溫度 400OC能在 ITO 與碳鋼上發現提高二氧化鈦的光催化能力，甚至能將腐蝕電流密度從 2.33×10-9降低至 5.09×10-11。而在鍛燒溫度600OC下，二氧化鈦的光催化能力會略下降，這歸因於其結晶結構開始發生了改變；但隨著不同摻雜量的柏金添加，二氧化鈦塗層於 ITO 玻璃上觀察到依然能提升其光催化效果。600OC處理後被覆於碳鋼上的效果改變不明顯，這可能歸因於高溫處理導致碳鋼氧化層脫落以及提及的鐵擴散問題，使二氧化鈦薄膜失效或脫落。此外在測試改以日光光源照射中，觀察到二氧化鈦光催化能力有限，ITO上400OC熱處理的二氧化鈦層仍能夠發現摻雜鉑金有提升其光催化能力，但被覆於碳鋼上則不明顯。而經600OC熱處理的光催化能力雖降低，被覆於 ITO 上摻雜鉑金變化卻有提升；但是碳鋼上是無法確認光催化能力的改善。最後分析了各種不同鉑金摻雜量的二氧化鈦薄膜被覆於碳鋼上的極化掃描，說明各條件下被覆層的抑制腐蝕狀況。本研究製備出摻雜鉑金的二氧化鈦塗層，對玻璃最優秀的表現是摻雜達 1.9×10-3
wt%並經過 600OC 熱處理能提升日光照射下的效果；而對於碳鋼，摻雜達 3.1×10-3
wt%並經過400OC 熱處理，紫外光照射最能抑制碳鋼腐蝕，600OC熱處理塗層會隨
氧化層剝落而失效，而日光下提升其光催化的能力有限。
