Title: | In situ fabrication of α-Bi2O3/(BiO)2CO3 nanoplate heterojunctions with tunable optical property and photocatalytic activity | Authors: | Huang, Y Wang, W Zhang, Q Cao, JJ Huang, RJ Ho, W Lee, SC |
Issue Date: | 2016 | Source: | Scientific reports, 21 2016, v. 6, no. , p. 1-9 | Abstract: | Exploring the full potential use of heterojunction photocatalysts containing bismuth has attracted considerable interest in recent years. Fabrication of well-defined heterojunction photocatalysts with precise modulation of their chemical composition is crucial for tuning their optical properties and photocatalytic activity. In this study, we fabricated nanoplate α-Bi2O3/(BiO)2CO3 heterojunctions through in situ thermal treatment of (BiO)2CO3 nanoplates synthesized using a facile hydrothermal process. Characterization results showed that the as-prepared Bi2O3/(BiO)2CO3 heterojunctions possessed distinct crystal interface and exhibited pronounced structural and optical modulation, resulting in significant improvement of their photocatalytic activity for NO removal under simulated solar light irradiation compared with pristine (BiO)2CO3. Electron spin resonance spectroscopy showed that OH radicals were the major reactive species involved in NO degradation, which is consistent with the theoretical analysis. The heterojunction formation can not only broaden the light absorption range but also improve the charge separation of photo-induced electron-hole pairs. This study is an important advancement in the development of semiconductor heterojunctions towards achieving functional photocatalysts. | Publisher: | Nature Publishing Group | Journal: | Scientific reports | EISSN: | 2045-2322 | DOI: | 10.1038/srep23435 | Rights: | This work is licensed under a Creative Commons Attribution 4.0 International License.
