| Abstract | A novel Bi2MoS2O4 nanoplate photocatalyst with high-energy efficiency and high-activity has been successfully synthesized by a reflux method. The visible-light response of Bi2MoS2O4 could extend from 480 to 630 nm compared with Bi2MoO6. Compared with Bi2MoO6, the photocatalytic activities of the Bi2MoS2O4 sample increased about 0.4 and 4.6 times for degradation of methylene blue (MB) under UV and visible-light (λ > 510 nm) irradiation, respectively. Density functional calculations revealed that Bi2MoS2O4 had a narrower band gap and wider valence bandwidth compared with Bi2MoO6 because S 3p orbitals contributed to the valence band formation. The high energy efficiency of Bi2MoS2O4 photocatalysts came from a narrow bandgap and the high activity came from a wider and dislocated valence band of Bi2MoS2O4. Furthermore, the synthesis of Bi2MoS2O4 could afford guidance for designing the other high-energy efficient and highly active photocatalysts. |
