Abstract
The heats of adsorption and desorption of hydrogen on a loaded titanium dioxide have been measured at 300 K by means of a Tian Calvet microcalorimeter. Differential heats of adsorption in the first run decrease from 40 to 3.5 kJ mol −1. Irreversibly adsorbed hydrogen is detected in all the adsorption-desorption cycles. Desorption shows differential heats that are always greater than the corresponding adsorption ones. Thermokinetic observations indicate diffusion of the adsorbate into the TiO 2 structure.
