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.
