Summary: A FeMnCe-activated semi-coke catalyst (FeMnCe/ASC) was prepared using semi-coke as the raw material. The structure and morphology of the catalyst were characterized, and its catalytic activity and stability were investigated. Under the optimal conditions, the degradation rates of ammonia nitrogen and COD reached 100%, and even after five times of recycling, the degradation rates still remained above 90%. The mechanism and pathway of piperazine degradation were also evaluated.

Summary: In this study, a robust dual catalyst of Ti-substituted LaFeO3 was synthesized for simultaneous photocatalytic wet peroxide oxidation to degrade carbofuran. The modified catalyst showed enhanced CBF degradation compared to the pristine LaFeO3 due to its reduced bandgap. Optimization of experimental parameters led to a 90.6% CBF removal rate within 180 minutes, demonstrating the catalyst's stability and efficiency.

Summary: Fenton or Fenton-like oxidation is a promising technology for treating organic radioactive wastes, although it has not been widely successful in mainstream treatment. The application of this process to real radioactive wastes has been documented in pilot-plant settings, showing potential benefits for higher volume or problematic organic wastestreams.

Summary: Five Fe/zeolite catalysts were prepared and tested in the catalytic wet peroxide oxidation process for the removal of three isomeric cresols. Fe/ZSM-5-3 exhibited the highest catalytic ability, attributed to the amount of framework-Fe and Fe3+Al-Si. The Fe/zeolites showed promising potential for degrading refractory contaminants in wastewater under mild reaction conditions.

Summary: The catalytic ozonation of Orange II using sulfuric acid modified aluminosilicate Montanit300 (MS) and hydrochloric acid modified Montanit300 (MH) showed high activity, with MH exhibiting better catalytic performance. The increased activity of MS and M under acidic conditions was attributed to manganese leaching. Additionally, MH displayed greater hydrophobicity, allowing for mild activity even under neutral conditions.

Summary: The ordered mesoporous alumina (MA) and Fe-doped MA were synthesized and tested for ozonation of sulfamethoxazole (SMX), showing superior surface and structural properties. Single ozonation effectively removed SMX and mineralized organics up to 35% at neutral pH, while the addition of MA or Fe-doped MA achieved up to 86% TOC removal at acid pH. However, ferric species did not improve the removal of organic matter under the selected operating conditions.

Summary: This study aimed to develop highly stable iron oxide foams for the continuous Catalytic Wet Peroxide Oxidation (CWPO) of micropollutants in a structured fixed-bed reactor. By adjusting the preparation methodology, homogeneity and adhesion of the active phase were achieved, resulting in three structured catalysts. Fe/Al2O3 and Fe/SiC exhibited outstanding catalytic performance in long-term operation, while Fe/ZrO2 showed deactivation due to iron leaching from the solid.
