Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute to our Special Issue on "Efficient Electro-Fenton-Catalysis" in Catalysts. The electro-Fenton process, which integrates electrochemical and Fenton reactions, has emerged as a promising approach for the degradation of organic pollutants in wastewater treatment. Given the increasing global concerns about water pollution and the need for sustainable waste management solutions, this research area is of paramount importance. Advances in electro-Fenton catalysis could significantly enhance the efficiency and applicability of this method, making it a key player in the field of environmental remediation. The primary objective of this Special Issue is to compile the latest research findings in the field of electro-Fenton catalysis, with a specific emphasis on enhancing the efficiency of the electro-Fenton process for the removal of persistent organic pollutants. We aim to investigate various aspects, including the design of catalysts, optimization of reaction mechanisms, and the influence of operational parameters on catalytic performance, thereby promoting the application of electro-Fenton technology in environmental remediation. We aim to curate a collection of at least 10 articles that will enhance the theoretical understanding of electro-Fenton processes while also highlighting practical applications and outlining future directions in this rapidly evolving field. This Special Issue will facilitate a comprehensive exploration of the current advancements and challenges in electro-Fenton catalysis, contributing meaningfully to the ongoing discourse in the field. In this Special Issue, original research articles and reviews are welcome.

Research areas may include (but not limited to) the following:

  1. Development of novel electro-Fenton catalysts, including nanomaterials and composites;
  2. Optimization of operational parameters for enhanced pollutant degradation;
  3. Mechanistic studies on electrochemical reactions in the electro-Fenton process;
  4. Integration of renewable energy sources in electro-Fenton systems.

We look forward to receiving your contributions.

Heterogeneous electro-Fenton (HEF) technology utilizing iron-based cathode catalysts has emerged as an efficient advanced oxidation process for wastewater treatment, demonstrating outstanding performance in degrading emerging organic contaminants (EOCs) while maintaining environmental sustainability. The performance of this technology is governed by two critical processes: the accumulation of H2O2 and the electron transfer mechanisms governing the Fe(III)/Fe(II) redox cycle. This review comprehensively summarizes recent advances in understanding the electron transfer mechanisms in iron-based HEF systems and their applications for EOC degradation. Five representative catalyst categories are critically analyzed, including zero-valent iron/alloys, iron oxides, iron-carbon/nitrogen-doped carbon composites, iron sulfides/phosphides, and iron-based MOFs, with a particular focus on their structural design, catalytic performance, and electron transfer mechanisms. A particular focus is placed on strategies enhancing Fe(III)/Fe(II) cycling efficiency and the interplay between radical (OH) and non-radical (1O2) oxidation pathways, including their synergistic effects in complex wastewater systems. Major challenges, including catalyst stability, pH adaptability, and selective oxidation in complex matrices, are further discussed. Potential solutions to these limitations are also discussed. This review provides fundamental insights for designing high-efficiency iron-based HEF catalysts and outlines future research directions to advance practical applications. Full article
