Volatile organic compounds (VOCs) from petrochemical, pharmaceutical, and other industries have serious damage to human health the environment. Catalytic oxidation is a promising method eliminate air pollution due its high efficiency, wide application range, environmental friendliness. However, in actual industrial environment, composition of exhaust gases complex, including VOCs, water vapour, chloride, sulfide so on. The impurities would competitive adsorption with reactants or react active sites, leading decline catalytic activity, even deactivation catalysts. Therefore, this review summarises recent research on anti-poisoning ability catalysts primarily focusing effect sulfide. mechanism manifested that activation are significant VOCs degradation. On basis, catalyst poisoning was analysed, inhibitory reaction elucidated. According status, three strategies proposed, building bimetallic system, modifying supports, establishing protected coating. This work provides theoretical foundation reference point for rational construction elimination.

Abstract Developing a new strategy to address water vapor poisoning is crucial for catalysts in real‐working conditions. Except the traditional thinking of resistance enhancement, reverse idea proposed herein utilizing inevitable H 2 O, converting it active ·OH enhance overall performance, with help O 3 and high energy electrons (e*) plasma. Dual sites Lewis acid (Y 3+ ) Mn on Y x y x+2y catalyst promote co‐adsorption , dissociation surface hydroxyl species (*OH). A OH‐accompanied pathway decomposition formed intermediate (*OOH) lower barrier (0.77 eV than *O 2− detected, which e* plasma can further accelerate its desorption. Thereafter, abundant are generated work pollutants degradation, achieving 99.78% ethyl acetate (EA) degradation 97.36% mineralization rate YMO (1:2) under humid environment, excellent long‐term stability. The changed activation site C─O bond EA, different by‐products, reaction pathways also analyzed. This regulation transforms poison effects into great benefits, paving way broader applications free vapor.
