Spinel ferrite nanostructures have played significant roles in the development of materials science and technology. Spinel ferrite nanostructures possess not only promising magnetic properties but also high resistivity, stability, and low eddy current losses. The recent progress in the utilization of spinel ferrite nanostructures for water remediation is reviewed with special emphasis on the adsorption, transformation, degradation, and catalytic reduction of nitroaromatics. Then, the structure–property relationships and design considerations of spinel ferrite nanostructures for catalytic applications are discussed in detail. Insights into the details of the various removal processes on the model spinel ferrite nanostructures are provided with a basic concept of nitroaromatics remediation. Subsequently, reaction kinetics and mechanisms are classified and their advantages and disadvantages are described. Lastly, challenges and future perspectives of spinel ferrite nanostructures for their practical applications are presented. With further advancement, spinel ferrites have potential to be practically utilized for a wide range of applications such as water treatment plants.

“…Thus, it is highly demanded to develop an efficient, cost-effective, and rapid technique to improve PNP degradation in aqueous environments. An advanced oxidation process (AOP) is considered a feasible approach to PNP removal 5 – 7 . Compared to the traditional AOP based on hydrogen peroxide, persulfate represents higher selectivity, lower reaction requirements, and milder conditions 8 .…”

The replacement of metals in catalytic processes is highly demanded to improve sustainability and economic growth. Poor stability and metal leaching are the main drawbacks of metal-based catalytic reactions. This work represented the use of nitrogen and sulfur-co-doped mesoporous carbon material ((N, S)-MPC) as a metal-free catalyst for the degradation of 4-nitrophenol (4-NP) as a priority pollutant announced by the Environmental Protection Agency through the persulfate-based advanced oxidation process. A low amount of (N, S)-MPC catalyst (0.3 g/L) exhibited superior performance for the degradation of 4-NP within 3 h at room temperature and unadjusted pH. The COD removal was calculated to be 76% using (N, S)-MPC catalyst. Interestingly, the degradations kinetics of 4-NP followed the zero-order kinetics with the rate constant of 0.505 min−1. The radical quenching experiment was accomplished to investigate the activation pathway of degradation. A real sample from an oil and gas company was treated with the (N, S)-MPC catalyst, which showed excellent total decontamination of 61%. The recyclability and stability of the catalyst have been evaluated for three runs. Owing to the obvious benefits such as high efficiency, metal-free nature, and recyclability, the presented catalyst can improve pollutant removal from aqueous media and practical environmental remediation.
