5 Hierarchical Self-Assembled Nanostructures for Adsorption of Heavy Metals Chemically selective surfactant molecules self- assemble within the interstices of a mesoporous silica matrix derived through solution processing routes. Resulting material shows high adsorption capacity for mercury and other heavy metals. Numerous environmental and commercial applications.
