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.
