Summary: In this study, it was found that applying a vertical magnetic field activated OH groups on the surface of ZnFe2O4 nanospheres, leading to increased adsorption capacity and degradation of toluene. The way in which toluene was adsorbed changed with increasing magnetic field intensity. These findings are important for understanding the role of OH groups and the effect of magnetic fields in the photocatalytic degradation of VOCs.

Summary: The ZnFe2O4/g-C3N4 (ZFOCN) step-scheme heterojunction synthesized in this study showed excellent performance for both adsorption and photocatalysis of U(VI) removal in aqueous solution. The adsorption process of U(VI) by ZFOCN and its photoreduction mechanism were investigated, and the results indicated that ZFOCN has strong visible light absorbability and a narrow band gap, leading to high removal efficiency and stability for U(VI).

Summary: Developing efficient and economical photocatalysts has been seen as an effective strategy for pollution remediation. In this study, magnetically separable ZnFe2O4/CuWO4 composites (ZW) were developed by combining ZnFe2O4 with CuWO4. The composite with a mass ratio of 40% CuWO4 (ZW-40) showed the best performance, with a tetracycline hydrochloride (TC) removal rate of 86.5% through adsorption-photocatalysis. The photocatalytic degradation rate constant of ZW-40 was approximately 5.04 and 3.28 times higher compared to ZnFe2O4 and CuWO4 samples, respectively. The improved photocatalytic capability was attributed to the formation of Z-scheme heterojunctions, enhancing light absorption and electron-hole separation. ZW-40 also exhibited high stability, with only a slight decrease in TC removal ability after 5 cycles. ZW-40 effectively removed TC in different water matrices, with the highest removal ability in super-pure water followed by municipal wastewater and swine farm wastewater. Therefore, the combination of ZnFe2O4 with CuWO4 offers a valuable strategy to enhance the photocatalytic potential of ZnFe2O4-based catalysts and provides a promising pathway for water clarification.

Summary: ZnFe2O4 is a promising photocatalyst in wastewater treatment, but its high recombination rate and metal ion leaching greatly limit its practical application. Carbon-coating strategy improved the photocatalytic performance by enhancing charge carrier separation and ozone utilization, and inhibiting metal leaching. Moreover, the carbon-coated ZnFe2O4 can be easily separated using an external magnetic field.

Summary: Emerging antibacterials contaminations in aquatic environment have posed acute and chronic toxicities to human health and increasingly disturbance to ecosystem and environment. One of the main sources of antibacterials residues is the pharmaceutical wastewater containing antibacterials with high concentration (100-500 mg L-1). In comparison with most photocatalysts competent for removing antibacterials with low-concentration (10-50 mg L-1), ZnFe2O4/Bi7O9I3 composites in our research have been utilized to effectively treat antibacterial wastewater with high concentration (100, 400 mg L-1).
