Mesoporous Carbon Based Composites for Removal of Recalcitrant Pollutants From Water

Abstract

Abstract Mesoporous carbon-based materials have been widely applied in the removal of aqueous recalcitrant pollutants owing to their unique chemical properties such as large surface area, ordered mesoropous structure and tunable pore size. In this chapter, on the basis of different types of functionalized mesoporous carbon-based materials, the synthesis strategies and properties of pure mesoporous carbons, metallic modified carbons and nonmetallic functionalized carbons are introduced. Moreover, the application of the three types of mesoporous carbon-based materials in recalcitrant pollutant removal are analyzed and discussed in detail. Pure mesoporous carbons are mainly used as adsorbents, catalyst activating persulfate and catalysts for microbial fuel cells. And heteroatom-incorporated mesoporous carbons, mesoporous carbon immobilized enzymes and other nonmetallic modified carbons are also used as adsorbents, oxygen reduction reaction (ORR) catalysts and anode catalysts in Microbial fuel cells (MFCs) and biocatalysts. While magnetic Fe-, Ni- and Co-doped mesoporous carbons are mainly used for recalcitrant pollutant adsorption, Pd, Pt, Ru, Ti-containing naoparticles supported on mesoporous carbons are applied as ORR catalysts in MFCs, catalysis for cellulose degradation, bromate and tetrabromobisphenol A removal and photocatalysis. In the end of this chapter, the future obstacles and perspectives of mesoporous carbon-based composites in recalcitrant organic pollutant removal are analyzed.
