Urbanization and industrialization have exerted significant adverse effects on water quality, resulting in a growing need for reliable eco-friendly treatment technologies. Persulfate (PS)-based advanced oxidation processes (AOPs) are emerging as viable technologies to treat challenging industrial wastewaters or remediate groundwater impacted by hazardous wastes. While the generated reactive species can degrade variety of priority organic contaminants through radical nonradical pathways, there is lack systematic in-depth comparison these pathways practical implementation different scenarios. Our comparative analysis reaction rate constants vs. indicates that radical-based AOPs may achieve high removal efficiency with relatively short contact time. Nonradical feature advantages minimal matrix interference complex wastewater treatments. (e.g., singlet oxygen, high-valent metals, surface activated PS) preferentially react bearing electron-donating groups, allowing enhancement degradation known target contaminants. For byproduct formation, analytical limitations computational chemistry applications also considered. Finally, we propose holistically estimated electrical energy per order (EE/O) parameter show significantly higher requirements pathways. Overall, critical comparisons help prioritize basic research PS-based inform merits system-specific applications.

Catalysts play a critical role in producing most industrial chemicals and are essential to environmental remediation. Under the demands of sustainable development, environment protection, cost-related factors, it has been suggested that catalysts sufficiently separable conveniently recyclable catalysis process. Magnetite (Fe3O4) nanomaterials provide possible way achieve this goal, due their magnetism, chemical stability, low toxicity, economic viability, etc. Therefore, Fe3O4-based materials emerging as an important solid support load heterogeneous immobilize homogeneous catalysts. Moreover, addition magnetic character will not only make recovery much easier but also possibly endow with desirable properties, such magnetothermal conversion, Lewis acid, mimetic enzyme activity, Fenton activity. The following review comprises short survey recent reports catalytic applications materials. It contains seven sections, introduction into theme, remediation, electrocatalysis, organic synthesis, synthesis biodiesel, cancer treatment, conclusions about reported research perspectives for future developments. Elucidation functions mechanisms Fe3O4 nanoparticles (NPs) these may benefit acquisition robust affordable protocols, leading good activity enhanced recoverability.
