摘　　要：考察了金属有机骨架材料CuBTC(BTC为均苯三酸)催化CO氧化的反应性能,发现CuBTC对CO氧化反应表现出良好的催化活性,且CuBTC样品的活化温度对其催化活性的影响很大.原位漫反射红外光谱、粉末X射线衍射、扫描电镜、热重分析和差示扫描量热结果表明,CO在CuBTC骨架中不饱和金属位点上的配位是加速CO氧化的主要原因,且这种不饱和金属位点越多,其催化活性越高.CuBTC（BTC = benzene-1,3,5-tricarboxylate）,an metal-organic framework（MOF）,is active for CO oxidation.The activation temperature has a significant effect on its activity.In-situ diffuse reflectance Fourier transform infrared spectroscopy,powder X-ray diffraction,scanning electron microscopy,and thermogravimetric analysis and differential scanning calorimetry（TGA/DSC） characterization showed that the coordination of CO on the open metal sites occurred during the oxidation reaction,and more open metal sites in the CuBTC framework gave a higher activity.
