Mesoporous carbon microspheres

This route may offer an alternative for the production of mesoporous carbon microspheres for use in, for example, adsorption techniques.

The preparation of mesoporous carbon foams was described recently [231]. By mixing an RF sol with polystyrene (PS) microspheres, followed by pyrolysis, a carbon skeleton of mesoporous carbon foam was obtained. 

The polymeric resins are substantially more hydrophobic than activated carbon. The non-wetting types are subjected to the pre-wetting procedure described above (i.e., wetting wi a solvent, such as methanol, followed by aqueous solution). The pores are presumably wetted (completely) upon this treatment. Undoubtedly, the mesopores (i.e., voids between the microspheres within each bead) are wetted. It is not clear, however, whether the micropores within each microsphere are completely wetted by this procedure.
