Summary:(001)-TiO 2 /BiOI photocatalysts with microsphere morphology were synthesized by a solvothermal method. The (001)-TiO 2 /BiOI demonstrated highest photocatalytic performance for the RhB degradation rate of 0.049 min −1 under visible light, which is 5 and 7 times that of (001)-TiO 2 and BiOI, respectively. The increased photocatalytic efficiency is due to the construction of heterojunctions, which promote the transportation of photo-generated carriers. The good photochemical stability of the prepared photocatalysts was demonstrated by cycling experiments. The radical quenching experiments show that &z.rad;O 2 − and &z.rad;OH are the principal active species in the photocatalytic reaction mechanism. Finally, a possible mechanism of p-n heterojunctions in the photocatalytic reaction process was proposed. (001)-TiO 2 /BiOI photocatalysts with microsphere morphology were synthesized by a solvothermal method.
