Tuning the selectivity of visible light-driven hydroxylation of benzene to phenol by using Cu, Fe and V oxides supported on N-doped TiO2

The Cu/N-TiO 2 photocatalyst produces phenol faster than the other formulated photocatalysts. No reduction in benzene conversion ( ca . 80%) and phenol yield ( ca . 25%) was observed after 4 reuses, confirming the high stability of the catalytic system.
