Crystal Structure Dependence for Reactivities of B₁₂-TiO₂ Hybrid Catalysts with Anatase and Rutile Forms

Crystal Structure Dependence for Reactivities of B₁₂-TiO₂ Hybrid Catalysts with Anatase and Rutile Forms

The debromination of phenethyl bromide by the $B_{12}-TiO_2$ hybrid catalyst under UV light irradiation was investigated. The catalytic efficiency was dependent on the type of $TiO_2$. The anatase form of $TiO_2$ was superior to the rutile form of $TiO_2$. The selectivity of the product was also dependent on the crystal structure of $TiO_2$, and the rutile form of $TiO_2$ showed a high selectivity for the formation of the coupling product, 2,3-diphenylbutane, when compared to that of the anatase form of $TiO_2$.
