近年來日本學術界開發分解水製氫的光觸媒有很大的進步,而其中以鉭銦氧化物為最具潛力應用的觸媒,這一系列觸媒主要是由日本東京理科大學的工藤昭彥教授所發展出來的。本計畫主要在配合核研所的計畫,從事有關觸媒的研究。本計畫目的在於,開拓太陽能利用的新途徑,建立世界領先的新能源技術。 本計畫分為上下半年執行:上半年:掌握雙光子光觸媒(Z scheme reaction)系列觸媒製備技術,及文獻收集。研製可見光雙光子光觸媒,初步建立其合成方法及鑑定。配合雙光子光觸媒研發,建立水分解實驗室型光化學反應器。 下半年:彙整雙光子光觸媒(Z scheme reaction)分解水產氫氣及氧氣之技術分析報告。對於雙光子光觸媒製程改善與精進,並配合氧化還原離子對選用,進行水分解效率測試。 我們將先對日本及其他研究者的研究進展廣泛收集資料,從事試製,並開發新的配方及製備技術,所製備之觸媒,除了在本校作物性、化性及反應測試外,將篩選出部分觸媒,大量製作,提供給核研所測試。 Photocatalytic water splitting to produce hydrogen over various In-Ta mixed oxide catalysts will beinvestigated. Tantalates possess conduction bands consisting of Ta5d orbitals at more negative positionthan titanates (Ti3d) and niobates (Nb4d). Such a high potential of the conduction band should beadvantageous to reduction of water to produce hydrogen. The aim of this proposal is to prepare the In-Taphotocatalysts according to the method reported in the literature. The preparation method and recipe will be modified. The catalysts will be examined by many surface chemical and physical technique and will be evaluated by the reaction of water splitting in the lab-scale. After screening, the best catalysts will be provided to the INER for large scle testing. It is expected that under the cooperation between this NCU and INER through this project, we will reach our mutual interest. The research results will be used as a new energy source in Taiwan. 研究期間:9501 ~ 9512
