摘要

本研究以燃燒合成法製備出赤銅鐵礦CuFeO2之奈米珊瑚狀結構，再將CuFeO2粉體做光觸媒產氫之研究。藉由Glycine不同比例添加，探討不同Glycine比例之粉末結構之影響及特性，並以X光繞射光譜儀、場發射電子顯微鏡、拉曼光譜儀、X-ray光電子能譜儀、TEM、BET、UV-Vis、光觸媒產氫、TG/DTA加以分析探討。以金屬硝酸鹽做為出發原料並添加不同比例之Glycine，將此前驅溶液加熱進行燃燒。本研究成功以低成本的燃燒法合成法製備出赤銅鐵礦CuFeO2奈米粉末。從X光繞射光譜儀、拉曼光譜儀和X-ray光電子能譜儀可得知燃燒合成法製備之化合物為赤銅鐵礦CuFeO2。FE-SEM表面形態下觀察得知其奈米性質與多孔性結構。BET分析其比表面積為6.26 m2/g。

The delafossite CuFeO2 nanopowder has been successfully prepared by glycine nitrate process (GNP), in this study, the crystal phase varied with glycine/nitrate ratio (GN ratio). A precursor solution was prepared by adding glycine with an aqueous solution of blended (Cu–Fe) metal nitrates in their stoichiometric ratios. In this method, we successful synthesis the low-cost of nanosized CuFeO2 powder. The powder was delafossite structure by X-ray diffraction and Raman, surface area of powder was 6.26 m2/g, as determined by BET surface area measurements. Field emission scanning electron microscopy studies on these powders confirmed their nanosized nature and porous structure.
