The average gold particle sizes on CeO₂ have been predicted by using plasmon bands detected from UV-Vis reflectance. In comparison to the pretreatment in H₂ or in H₂O vapor, Au/CeO₂ pretreated in CO at 200°C would generate gold particles with smaller sizes and with higher activity during WGS reaction.
