BiOI/NaBiO3 heterostructure photocatalysts were synthesized using HI as etching agents to react with NaBiO3 by a heating condensate reflux method according to surface chemical etching principle. Several characterization tools including X-ray powder diffraction (XRD), scanning electron microscope (SEM) and UV-Vis diffuse reflectance spectra (UV-Vis DRS) were employed to study the phase structures, morphologies and optical properties of the as-prepared samples respectively. From the degradation of Rhodamine B(RhB) under visible light irradiation experimental results, we can obtained that the absorption capacity of as-prepared samples were enhanced with increasing the BiOI amounts in the BiOI/NaBiO3 heterostructures until the BiOI/NaBiO3 ratio is 79.62%. With increasing BiOI content, the photocatalytic activity enhanced gradually and then decreased. As the BiOI content increase to 17.34%, the highest photocatalytic activity could be achieved, and the RhB almost faded completely with the time increasing to 100 min. The results show that the adsorption ability is only a factor not all to promote the photocatalytic ability. The EVB of NaBiO3 and BiOI were calculated to be 2.23 and 2.41 eV and the ECB of NaBiO3 and BiOI were -0.23 and 0.46 eV by the UV-Vis DRS method respectively. To evaluate the roles of reactive species during photocatalysis, different scavengers including benzoquinone, isopropyl alcohol and methanol were adopted as the traps for O2-, OH and h+ for RhB degradation. The results suggesting that h+ played major role for RhB degradation. Terephthalic acid photoluminescence (TA-PL) probing test demonstrated that OH could be negligible also. According to the band gap structure of BiOI/NaBiO3, the effects of scavengers and the PL experimental results, a possible charge separation processes between BiOI and NaBiO3, and the pathway for the photocatalytic activity enhancement mechanism was proposed. The heterojunction at the interface between p-BiOI and n-NaBiO3 can efficiently reduce the recombination of photogenerated electron-hole pairs and which accounts for the enhancement of photocatalytic activity. Form the analysis of potential, it is theoretically reasonable that the photocatalytic degradation of RhB could be attributed to the reaction of hole directly rather than OH and O2- radicals.
