Abstract
The adsorption of CO on polycrystalline TiO 2 was investigated by static adsorption microcalorimetry. The initial differential heat of adsorption (q diff,0) of CO on polycrystalline titania is 40 kJ/mol, and the standard adsorption entropy (Δs 0) is -104 J mol -1 K -1. These results are consistent with those derived from temperature-programmed desorption and FTIR results in the literature. The good reproducibility of the isotherms and the stable q diff indicate that the lattice oxygen and hydroxyl groups on titania surface are basically not reactive to adsorbed CO.
