Solid-state NMR studies of nanoporous carbons

      Nanoporous carbon materials are or large interest for
electrochemical applications, catalysis and gas storage, among many
other uses. These materials are commonly produced by means of
activation processes involving reaction with chemical agents. After
activation, it is usually found that surface groups exist within the
nanopores of the material, which in many cases involve the bonding
between the carbon network and “inorganic” elements present in the
chemical activating agent (such as K, Na and P). In this work, we
investigate a series of porous carbons prepared using different
chemical reactants, mainly using solid-state NMR methods in a
multinuclear approach. The purpose of this investigation is to
identify the nature of these groups and the possible interaction
between the extraneous elements and the carbon-based, graphene-like
planes.
