Abstract Advanced Oxidation Processes (AOPs) are promising for treating persistent pollutants, yet challenges arise due to the step-wise oxidants activation process, which traditional single-active-center catalysts struggle facilitate effectively. Recently, dual-active-center have emerged as a solution by enabling synergistic reactions. This review covers advances in these catalysts, their co-catalytic mechanisms, and applications electro-Fenton, photocatalytic, peroxymonosulfate-, pollutant-as-electron-donor based Fenton-like processes, along with active site design considerations future challenges.

The use of hydrogen peroxide (produced in situ or ex situ) as the main agent oxidative processes environmental pollutant removal is widely studied. degradation water pollutants, such dyes, pharmaceuticals, cosmetics, petroleum derivatives, and even pathogens, has been successfully obtained by different techniques. This review gives an overview more recent methods developed to apply mediated H2O2 other reactive oxygen species (ROS) catalysis, with particular attention strategies (Fenton-like Bio-Fenton, photo- electro-catalysis) materials employed. A wide discussion about characteristics specifically studied for activation, well their chemical composition morphology, was carried out. Moreover, interesting generation enzymes were also presented efficiency applicability compared Fenton electro-Fenton discussed above. Bio-Fenton bi-enzymatic ROS seems be attractive scalable, although not yet applied full-scale plants. critical feasibility, criticalities, perspectives all considered completes this review.
