Published on by Hossein Ataei Far, Deputy Manager of the Research, Technology Development, and Industry Relations Center at NWWEC
🌍Introduction:
Electrochemical advance oxidation processes (EAOPs) like electro-Fenton (EF) and photoelectro-Fenton (PEF) play a crucial role in eliminating persistent organic pollutants (POPs). However, their limitations, especially at strong acidic pH conditions, prompted the exploration of Heterogeneous electro-Fenton (Hetero-EF) processes using solid catalysts. This review delves into the advantages, mechanisms, configurations, and applications of Hetero-EF, addressing the challenges and prospects in wastewater treatment.
Methodology: The review extensively discusses the fundamental principles, mechanisms, and configurations of Hetero-EF processes. It highlights the features of good heterogeneous catalysts, delving into synthesis routes for solid catalysts and functionalized cathodic materials. Additionally, it explores the application of Hetero-EF in bioelectrochemical systems, providing insights into challenges and prospects.
🌍Key Findings:
▶️ Hetero-EF processes overcome pH limitations, making them applicable across a wide pH range.
▶️ Solid catalysts and functionalized cathodic materials enhance reusability and widen the pH window in Hetero-EF.
▶️ Various classes of solid catalysts and iron-functionalized cathodic materials prove successful in Hetero-EF wastewater treatment.
▶️ Bioelectro-Fenton technology, utilizing microbial fuel cells, offers concurrent electricity generation during Hetero-EF treatment.
🌍Implications: Hetero-EF presents significant implications for wastewater treatment, providing a versatile and efficient solution for degrading and mineralizing diverse organic pollutants. The use of solid catalysts and functionalized cathodic materials enhances sustainability and applicability in various contexts.
🌍Conclusion and Keynote Summary:
In conclusion, Hetero-EF processes based on Fenton's chemistry emerge as a promising and efficient technology for wastewater treatment. The review underscores their advantages, mechanisms, configurations, and applications, emphasizing the crucial role of solid catalysts and functionalized cathodic materials.
