Abstract :
Volatile organic compounds (VOCs) have attracted worldwide attention due to their serious risks to the environment and human health. Industrial processes such as the combustion of fossil fuels, petrochemicals, dyes, coatings, pesticides, and plastics all contribute to the emission of VOCs. Degradation methods (catalytic oxidation and biofiltration) and recovery methods (adsorption, compaction, and membrane separation) have been developed to remove VOCs. Adsorption has been established as one of the most promising strategies to reduce VOCs due to its cost-effective properties, simplicity, and low energy consumption. Prominent advances in the adsorption of VOCs by various types of porous materials (such as carbon-based materials, oxygen-containing materials, organic polymers, and composites) have been carefully summarized in this study. This study aims to provide a comprehensive understanding of the mechanisms of VOCs adsorption for different porous materials.
