摘要

氣候的變遷及能源短缺提升了對於溫室氣體減量與能源回收的關注，利用光催氫化CO2成為有機化合物，以達到降低大氣中CO2的濃度與產生具價值再生能源的最佳路徑為”人工光合作用”；而其中最關鍵的部分為氫化CO2生成有機物。本研究探討一系列CO2光催氫化觸媒，將溶膠凝膠法製備而成的InTaO4負載NiO, RuO2, Cu(OH)2 and Pt氧化金屬助觸媒。由UV-Vis圖譜得知銦鉭觸媒可吸收至可見光波段，添加NiO共觸媒且經還原---氧化前處理後增進了其在可見光波段的吸收，並經XRD pattern確認晶相、XPS確認表面助觸媒型態；利用AM1.5 G模擬太陽光於常溫下在通入CO2與水氣時獲得乙醛0.25μmol/g

Global warming and energy shortage raising the concern about green house gases reducing and energy recovery. One of the best routes to covert CO2 into renewable energy and reduce the concentration of CO2 in atmosphere is artificial photosynthesis. The first key step may rely on the hydrogenation of CO2 to organic compounds. This study explored the photocatalytic hydrogenation of CO2 under light irradiation. A series of sol-gel prepared InTaO4 were loaded with different metal oxide such as NiO, RuO2, Cu(OH)2 and Pt were as co-catalysts. The UV-VIS spectra of this series catalysts indicated that the photocatalysts could absorb visible light. The maximum yields of acetaldehyde and methyl formate were 0.25 and 0.16 μmol/g
