Advanced Carbon Aerogels for Energy Applications
yield a macroporous CA containing periodic voids, the diameter of
which is controlled by the size of the template spheres. Using this
technique, materials with bimodal pore structures can be prepared
in which the large ordered cavities (d = 0.1–1 mm) formed by the
template are continuous and interconnected, while smaller meso-
and microporous channels run continuously throughout the aerogel
wall. Hierarchically porous structures of this type present a number
of advantages over unimodal carbon structures in terms of diffusion
