Περίληψη: Methyl mercaptan (CH3SH) is a malodorous and toxic gas commonly emitted from petrochemical, pharmaceutical, and wastewater treatment industries. Due to its low odor threshold and contribution to secondary atmospheric pollution, its effective removal is essential. Traditional methods, such as adsorption, absorption, biodegradation, and non-thermal plasma, often suffer from limitations in efficiency and stability. Catalytic technologies have garnered increasing attention for their high removal efficiency, low energy consumption, and environmental compatibility. This review highlights recent advances in the gas-phase catalytic elimination of CH3SH, focusing on reaction mechanisms, catalyst design, and performance metrics. Special emphasis is placed on strategies such as oxygen vacancy engineering, modulation of metal oxidation states, and interface/defect tuning to enhance catalytic activity and durability. Key performance factors are discussed, and current challenges are critically evaluated. Finally, future research directions are proposed to support the development of efficient and sustainable CH3SH abatement technologies.
