Carbon hybridized montmorillonite nanosheets: preparation, structural evolution and enhanced adsorption performance

Abstract

Carbon hybridized montmorillonite nanosheets (C/MMT) were successfully prepared by mixing intercalation, hydrothermal carbonization and calcination pyrolysis of montmorillonite and sucrose. The amount adsorbed on C/MMT reaches 0.84 g g⁻¹ at a Congo red concentration of 1.0 g L⁻¹, which could be attributed to their special structures and synergistic sorption.
