Ceria nanorods were investigated using in-situ Raman and FTIR spectroscopy for CO adsorption and subsequent reaction with water at 200 °C and 350 °C. The involvement of defects in ceria nanorods during CO adsorption and reaction with H2O is dependent on the temperature. At 200 oC, most of the carbonate and formate species formed in CO do not involve the creation of defects, while at 350 oC all of the carbonates and formates formed are related to the creation of defects (15% by formates and 85% by mono/bi-dentate carbonates). Finally, at 350°C very stable poly-dentate carbonates are formed that do not induce defects and cannot be regenerated with water.
