Abstract

Cu₃(BTC)₂ catalyst loaded with Ag nanoparticles was successfully prepared through UV reduction method, and was applied for NH₃-SCR reaction. The physicochemical properties of Ag/Cu₃(BTC)₂ catalyst were characterized by XRD, TEM and BET. It was found that Ag nanoparticles showed a pherical structure and were highly dispersed on the skeleton structure surface of Cu₃(BTC)₂. The synergistic effect between Ag nanoparticles and Cu-MOF could significantly improve the denitrification efficiency of Ag/Cu₃(BTC)₂ catalyst. The Ag/Cu₃(BTC)₂ catalyst with 15wt% addition achieved a 100% NO conversion rate in temperatures range from 200 to 260℃. Furthermore, the reaction mechanism was proposed on basis of the results of in situ Fourier transform infrared spectroscopy.

Key words： selective catalytic reduction metal organic frameworks Ag loading nitrogen oxides
