Abstract
Gold nanoparticles dispersed on MnOx/TiO2 were used to perform the oxidation of carbon monoxide at low temperatures. Remarkable dispersion of gold nanoparticles under hydrogen treatment was obtained, mainly in Au–MnOx/TiO2 catalysts with 2 wt% Au and 5 wt% Mn, where the Au nanoparticles displayed average sizes of 1–3 nm. The addition of Au nanoparticles to the MnOx/TiO2 catalysts promoted both the CO oxidation from 0 °C and stability at room temperature. This behavior could be attributed to the synergistic interactions between Au0/Au1+ and Mn3+/Mn4+ on the Au–MnOx/TiO2 catalyst surface.
