Silica has a long history of service to humankind in the making of glass, abrasives, reinforced composite materials, sorbents, and catalysts. In these applications, the interfacial chemistry of the silica surface, as well as the surface area provided by the particle morphology, are critical to the success or failure of the final product. Over the years, much effort has been expended in exploring the interfacial chemistry of silica, as well as manipulating particle size and morphology of the silica in an effort to enhance the surface-area-to-mass ratio. Recent advances in the areas of nanostructured ceramics and molecular self-assembly have provided the key components to what is, perhaps, the ultimate refinement in catalyst support and sorbent design.
