1. A method for producing a nanostructure with a specified diameter or cross-sectional area, comprising: specifying the diameter or cross-sectional area of the nanostructure; selecting a mesoporous siliceous framework having pores with a pore size that has a predetermined dimensional relationship with the diameter or cross-sectional area of the nanostructure, said mesoporous siliceous framework containing metal ions dispersed in substitutional sites and forming a source of catalytic sites; and contacting, in a reactor, the mesoporous siliceous framework with a reactant at a temperature sufficient to produce the nanostructures with the specified diameter or cross-sectional area.
