Summary: In this study, a CoFe2O4/kaolinite (CFO/K) composite photocatalyst was successfully synthesized, and tetracycline hydrochloride (TCH) was degraded through synergetic photo-Fenton reaction. Compared with pure CoFe2O4, CFO/K-40% exhibited higher photocatalytic degradation efficiency due to its larger specific surface area, abundant surface active sites, and higher photogenic electron hole pairs separation efficiency.

Summary: Effective heterogeneous catalysts for the removal of refractory organic pollutants are highly desirable. In this study, FeOOH/BOBC-2 hybrids were found to exhibit superior performance as photo-Fenton catalysts for tetracycline hydrochloride degradation. Factors such as catalyst dosage, TCH concentration, H2O2 amount, and initial pH were investigated and found to significantly affect the performance of the catalyst. Enhanced specific surface areas and effective charge separation were key contributors to the improved photo-Fenton performance.

Summary: A Fe/graphitic carbon nitride/kaolinite composite photocatalyst was successfully prepared for the first time and showed high degradation efficiency for TCH in the photo-Fenton system. Free radical scavenging experiments confirmed that hydroxyl radicals were the main active substances. The enhanced photocatalytic activity of the composite can be attributed to the large specific surface area of kaolinite and Fe acting as a photo-generated electron acceptor.

Summary: In this study, α-Fe2O3/MIL-53(Fe) composite was successfully prepared and used as a photo-Fenton catalyst for the degradation of TC-HCl. The composite exhibited excellent performance in TC-HCl degradation due to the synergistic effect between MIL-53(Fe) and α-Fe2O3. The heterojunction structure formed in the composite played a crucial role in reducing the band gap, enhancing visible light absorption, and improving the separation and transportation of photo-induced carriers.

Summary: This work presents a facile green synthesis method for producing Fe3O4 magnetic nanoparticles (MNPs), which exhibit high catalytic activity in Fenton and photo-Fenton reduction reactions. The MNPs show spherical morphology and have an average diameter of 6.3 +/- 1.1 nm. The study demonstrates the superior efficiency of the MNPs in both processes at varied pH ranges. Additionally, the MNPs exhibit good reusability and can effectively reduce dye and Cr(VI) loads in water treatment processes.

Summary: Ce-doped BiFeO3 precursors were synthesized and Ce-doped BiFeO3 (BCFO) was obtained through high-temperature calcination. Ce doping reduced the band gap of BiFeO3 and enhanced the photocatalytic performance. The photocurrent density, impedance, and saturation magnetization of BCFO increased significantly. BCFO-7 (7% Ce doping) showed excellent catalytic activity in the degradation of tetracycline, with a high detoxification effect and stable photocatalytic process.
