The catalytic properties of titanium dioxide-supported catalysts in n-hexane isomerization reactions have been studied. The hexane isomerization activity was found to increase in the series Fe/TiO2 < Ca/TiO2 < Ni/TiO2. The most active Ni/TiO2 catalyst is effective in two temperature ranges: moderate temperatures (150-300°C) for a bond shift mechanism and high temperature (350-400°C) for a cyclic mechanism with intermediate five-membered ring information along with a bond shift mechanism. The formation of dispersed nickel leading to a hydride phase during the reductive activation of Ni/TiO2 was proposed. Ionic hydrogen and nickel facilitate enhanced Ni/TiO2 catalyst activity.
