Advances in Studies on the Adsorption of Dyes in Wastewater using Mesoporous Materials

Due to their large surface areas, high pore volumes, relatively even distributions of pore sizes, surfaces enriched with unsaturated groups and orderly long-range structures, the mesoporous materials have been widely applied in industries such as chemical, biomedical, environmental protection and functional materials. In recent years, many scientists have demonstrated that the mesoporous molecular sieves have better adsorption of dyes in wastewater. This paper reviews the applications of different types of mesoporous adsorbents for removal of dyes in wastewater. It also presents the challenges and prospects in using the mesoporous materials for dye removal in wastewater treatment.
