摘要

Volatile organic compounds (VOCs) are significant pollutants in both indoor and outdoor environments, posing serious health hazards and contributing to environmental degradation. This review explores recent advances in air-purification technologies for removing VOCs. It provides a comprehensive analysis of various methods, including adsorption, catalytic oxidation, photocatalysis, biofiltration, and membrane separation, with a focus on their mechanisms, materials, and performance. All methods demonstrate high VOC removal efficiency, ranging from 50 to 100% under different conditions. The review also addresses key challenges associated with large-scale implementation, including material constraints, energy requirements, and economic viability. Future directions emphasize the development of hybrid systems and the integration of emerging technologies, particularly artificial intelligence-based optimization, to enhance efficiency and sustainability.
