    • "Nanopore" and "nanoporous" have been used in the recent literature to describe pores that range anywhere in size from one to hundreds of nanometers; as descriptors of space through which molecules transport, these terms are meaningless.

    • note
    • The nanoparticles in an aerogel network provide a large surface area for heterogeneous reactions, but they are constrained in mobility by being a covalently bonded network; the high dilution of nanoparticulate solid in the volume of the gel also stabilizes oxide aerogels to sintering.

    • Gold-MPCs, which are processible as dry chemicals, can be incorporated into the construction of a composite nanoarchitecture at any stage: during sol-gel synthesis, after gel formation, or even by adsorption to the through-porous oxide after drying and processing.

    • With pore openings of ∼1 nm, the inner surfaces of carbon single-walled nanotubes are not expected to contribute to the total electroactive surface area.

    • If a carbon-silica composite gel is prepared and then soaked in a 1.8-nm Pt sol, the Pt colloids do not adsorb to the carbon, indicating that the silica colloids anchor at the same sites on Vulcan carbon at which the Pt colloids adsorb.
