Abstract: 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.

Key words: metal-organic framework, copper benzene-1,3,5-tricarboxylate, carbon monoxide, activation condition, gas-solid catalysis
