Abstract | In recent years, spinel-type ferrites have promising application prospects in the field of photocatalysis. However, its agglomeration will affect the catalytic effect, and the construction of a heterojunction structure can effectively improve the catalytic efficiency. In this study, a series of BiWO/NiFeO p-n type heterojunctions (NiFe-Bi-XY) by self-assemble were prepared and used to remove tetracycline in water. In the sunlight/NiFe-Bi-73/permonosulfate (PMS) systems, yhe optimal removal efficiency towards 20 mg·L tetracycline could reach 91.1% at 30 min, and the mineralization rate was 56.3%. The constructed reaction system still maintained a good removal effect of tetracycline in an alkaline environment. For NiFe-Bi-XY, the formation of p-n type heterojunctions was proved by XPS valence band spectra, Kubelka-Munk plots, Mott-Schottky test and ESR measurements. In this system, the degradation of tetracycline was mainly achieved by photocatalytic and non-photocatalytic pathways. Radical trapping experiments confirmed that ·O and O radicals were the most critical active species during the catalytic process. This study provides a feasible approach to synthesize efficient binary heterojunction catalysts for environmental remediation. |
