Abstract:
We report an efficient method for the synthesis of organo-functionalized mesoporous silica nanospheres (MSNs) with high-level organo-functionalization using TEOS and chlorosilanes as precursors. The phenyl-functionalized MSNs with superhydrophobic surface properties could efficiently adsorb organic pollutants from water.
