DESIGN, SYNTHESIS AND CHARACTERIZATION OF ORDERED MESOPOROUS MATERIALS FOR ENVIRONMENTAL APPLICATIONS

摘要

Since the first report on the MCM-41 silica in 1992 several thousands of papers have been published on ordered mesoporous materials (OMMs). These novel materials, prepared either by soft- or hard-templating syntheses, become more and more important in many fields of science and technology such as adsorption, catalysis, separations, environmental processes, nanotechnology and biotechnology. The aim of this article is to provide a brief review on the OMMs design and synthesis as well as to show potential of these materials for various environmental applications such as sequestration of carbon dioxide, removal of gaseous organic and inorganic pollutants via adsorption and catalytic degradation, removal of heavy metal ions from contaminated water, and so on. The scope of environmental applications of OMMs is broad and continuously growing. The soft- and hard-templating syntheses create great opportunities for the design of OMMs such as ordered mesoporous silicas, organosilicas and carbons with desired surface and structural properties and for their use in various environmental processes.
