Abstract
Use of FT-IR spectrometry coupled to gas chromatography evidenced two temperature stages for the reduction of ceria by CO: (i) below 300 deg rees C, surface reduction occurred and mainly involved formate species as intermediate,(ii) above 300 degrees C, subsurface reduction involv ed terdentate carbonates.
