Abstract

Abstract

Heterogeneous Fenton oxidation， a representative advanced oxidation technology， primarily degrades organic pollutants by activating H₂O₂ to generate highly oxidative reactive oxygen species， such as hydroxyl radicals. This method has been widely applied in the advanced treatment of industrial and domestic wastewater. Iron-based heterogeneous Fenton catalysts have gathered significant research interest， due to their eco-friendliness and low cost. However， challenges such as low catalytic efficiency and a narrow applicable pH range remain. In recent years， substantial efforts have been made to broaden the pH range and enhance the catalytic activity of iron-based heterogeneous Fenton catalysts， effectively addressing some limitations of the Fenton oxidation process. This review systematically introduces the fundamental principles of heterogeneous Fenton oxidation and the mechanisms for extending its pH applicability. It also summarizes recent advances， both domestically and internationally， in strategies such as the introduction of external physical fields， chemical auxiliary agents， and internal structural regulation of catalysts to broaden the pH range. Additionally， it highlights critical scientific issues that need to address and discusses future research directions， providing valuable insights for developing high-activity iron-based heterogeneous Fenton catalysts with a wide pH applicability.
