Abstract
- Herein, a series of covalent triazine framework/bismuth vanadate (CTF/BiVO <subscript>4</subscript> ) heterojunction catalysts were prepared using the hydrothermal method. The mechanism of the CTF/BiVO <subscript>4</subscript> heterojunction photocatalyst in the system was examined to provide a theoretical basis for constructing a high-efficiency photocatalysis composite system for removing organic pollutants from water. Compared with CTF and BiVO <subscript>4</subscript> catalysts alone, composite materials have been shown to have significantly higher degradation efficiencies against organic pollutants in water. Moreover, the degradation effect was found to be optimal when the mass ratio of CTF to BiVO <subscript>4</subscript> was 1:1 (1-CTF/BiVO <subscript>4</subscript> ). On the basis of physicochemical characterization results, it was concluded that the effective construction of CTF/BiVO <subscript>4</subscript> composite photocatalyst material systems and the formation of type II heterojunction structures between CTF and BiVO <subscript>4</subscript> effectively promote the separation of photogenerated carriers and increase the interface charge transfer efficiency.<br /> (© 2022.
