In the catalytic oxidation of atmospheric pollutants such as volatile organic compounds (VOCs), catalyst deactivation induced by water under realistic operating conditions has emerged as a critical bottleneck constraining the large-scale application of this technology. This review aims to provide a systematic global perspective for developing highly efficient and water-resistant catalytic materials for the oxidation of atmospheric pollutants. First, the underlying mechanisms of water-induced catalyst deactivation in humid atmospheres are dissected in depth from the perspectives of micro-kinetics and thermodynamics, and critical evolution processes including competitive adsorption initiated by polar water molecules, poisoning by surface persistent hydroxyl groups, blockage of active oxygen recycling, and irreversible hydrothermal reconstruction on the macroscale are systematically delineated. Subsequently, recent frontier materials design strategies to enhance the water resistance of catalysts are reviewed, with emphasis place on elucidating the structure-activity relationships behind the development of single-atom catalysts, modulation of metal-support interactions (MSI), exploitation of bimetallic synergy, modification of metal oxides, regulation of crystal structures, and utilization of metal-organic framework (MOF) derivatives, as well as photo/photothermal and ozone-assisted catalysis. Finally, the core challenges associated with the current water-resistant catalytic technologies for their industrialization are summarized, aiming to provide solid theoretical support for rational research.
