Catalizadores emergentes para oxidación avanzada catalítica de ozono en la purificación de agua: marcos...

With the increasing severity of environmental problems, ozone-based advanced oxidation processes have gained widespread attention in water purification due to their strong oxidizing properties and potential for reducing secondary pollution. Among the various methods of catalytic ozonation, heterogeneous catalytic ozonation (HCO) has been shown to be an effective strategy. Metal-organic frameworks (MOFs) with large surface area, ultra-high porosity, and versatility in material design have been widely used in non-homogeneous catalysts, and in recent years, significant efforts have been made to utilize MOF-based materials. This paper presents a comprehensive review of the latest research on MOF-based catalysts for the ozonation removal of emerging contaminants (ECs) and organic pollutants. The review also explores structure-activity relationships and mechanisms of action, emphasizing how the tunability of MOFs provides a novel approach to overcoming the limitations of conventional ozone catalysts, such as low efficiency and metal leaching, particularly through the design of bimetallic systems and stable derivatives. This research is expected to inform the rational design of next-generation catalysts and promote their practical application in water purification.
