Title
Enhanced CO oxidation over thermal treated Ag/Cu-BTC
Abstract

•Ag/CuxO nanoparticles are formed by thermal treatment of Ag/Cu3(BTC)2.•The thermal treatment operates at atmospheric pressure under O2 atmosphere.•Synergy between CuxO and Ag leads to enhanced activity for CO oxidation.•CuxO species are helpful for CO adsorption.•Ag plays a key role in the activation of oxygen.

Thermal treatment of Cu3(BTC)2 supported Ag has been performed at 250 °C and ambient pressure under oxygen atmosphere. Ag/CuxO (x = 1,2) nanoparticles are obtained. The catalyst characterization shows that CuO and Cu2O species are helpful for CO adsorption and Ag plays a key role in the activation of oxygen. The synergy between CuxO and Ag leads to significantly enhanced activity for CO oxidation. In addition, Ag is partially oxidized by oxygen and Ag2O probably acts as one of the active species for CO oxidation.
