ABSTRACT
Porous materials such as porous ceramics, porous metal, and porous plastics are widely used as catalytic support, adiabatic material, ltrate material, absorbent material, and so on.1 Nanopore glass is one kind of inorganic porous material. In this chapter, nanopore is dened for pores with diameters less than 50 nm. Nanopore materials such as nanopore glass are expected to have remarkably exotic properties that are different from those of conventional porous materials. For instance,
