Abstract:		"Volatile organic compounds (VOCs) are harmful contaminants that are emitted into the environment as a result of various commercial, industrial, and domestic practices. Their presence in water leads to pollution and poses a huge threat to the ecological environment and human health. They are typically released into the environment through a spill or inappropriate disposal which allows the chemicals to get absorbed into the ground or enter the sewage system. Thus far, several treatment methods have been developed to remove VOCs from water, including steam stripping or air stripping, ion exchange, filtration, adsorption, and application of various types of sorbents. Due to their cost-effectiveness and efficiency, the use of mesoporous materials, especially those synthesized from coal fly ash (FA), is recognized as the most promising strategy for slowing down the impact of VOCs. This study is believed to be the first to assess the advances made in improving the adsorption of VOCs by different functional mesoporous materials (FA, zeolites, mesoporous silica, metal organic frameworks). The impact associated with the properties of these materials is carefully summarized in this paper, in regard to their solid-state characteristics, material synthesis method, and surface modification. In addition, their chemical and physical interactions in solution, the reaction kinetics, and the influence of temperature and pH are described in detail. The aim of this work was to compare the sorption properties of the materials synthesized from FA with more complex mesoporous materials. This overview provides a comprehensive understanding of VOC removal from water systems using various functional materials, as well as helps in identifying the materials that may play a key role in the future"
