CO oxidation on nanosized Au/Al2O3 by surface hydroxyl groups and in the absence of O2, studied by inverse gas chromatography

- Studying the sorption of CO over bare γ-Al2O3 and Au/γ-Al2O3, by RF-IGC.
- Compare the kinetics, adsorptive capacity and the nature of the active sites.
- Stronger binding of CO molecules over γ-Al2O3 at higher temperatures.
- Gold enhances the sorption of bigger amounts of CO.
- CO decomposition indicates a “periphery” mechanism with surface hydroxyl ions.
