Abstract
Photocatalytic technology is widely used to remove environmental pollutants, and the development of high-performance photocatalysts is an important prerequisite for boosting photocatalytic processes. Herein, Sn-doped Bi2MoO6 nanosheets were constructed by one-step solvothermal method. The experimental results indicate that the Sn doping not only tunes the band structure of Bi2MoO6, but also effectively promotes the photogenerated charge separation, thus providing abundant free charge for photocatalytic reactions. The optimized Sn-Bi2MoO6-2 sample shows the degradation efficiency of TC and MBT reaching 81% (for 3hours) and 85% (for 2hours), respectively, and the removal efficiency of Cr(VI) is 1.5 times compared with that of pristine Bi2MoO6. Moreover, the experiments with different pH, inorganic cations and anions were carried out to investigate the practical application potential of the photocatalyst, and the Sn-Bi2MoO6-2 also exhibits excellent photocatalytic performance for decomposing antibiotic contaminants in river water. Furthermore, mass spectra and radical trapping experiments explored the possible photocatalytic degradation processes. This work explored the multiple positive roles of Sn-Bi2MoO6 materials in the photocatalytic system, which provides a promising strategy for constructing efficient photocatalysts for environmental remediation.
