Geopolymer spheres made from metakaolin and rice hull ash have exceptional chemical and mechanical stability, making them promising catalyst support matrix for photoactive compounds. In this paper, titania was deposited on geopolymer sphere via horizontal vapor phase growth method, which produced nanotitania crystals embedded on the surface. The titania-coated geopolymer spheres resulted in 90% dye photodegradation activity that can be used repeatedly, thus qualifying the products as sustainable materials for wastewater treatment.

Different Types

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.

Promising Application

Cr(VI) has a highly toxic effect on the organism and has caused serious harm to the environment. Due to quantum size effects and interface coupling effects, mesoporous materials have novel physical, chemical and many other excellent performances, especially for the promising application in the adsorption of heavy metals. This article includes a survey of removal mesoporous materials for Cr(VI)-contaminated wastewater. It also presents the challenges and prospects in using the mesoporous adsorbents for Cr(VI) removal in wastewater treatment.
