Kinetic studies of CO ₂ dissociation on supported Ni catalysts

Summary

In order to investigate the kinetics of CO₂dissociation on supported nickel catalysts, a novel technique, which can give the surface reaction rate constants with no information on the number of active sites, was developed. It was revealed that CO₂dissociation was more enhanced on TiO₂support than on other metal oxide ones. The activity pattern and activation energies were in good agreement with those obtained by a conventional pulse technique using the number of active sites, suggesting the validity of the present technique for investigating the kinetics of the surface reaction.</o:p>
