Abstract
Porous carbons have several advantageous properties with respect to their use in energy
applications that require constrained space such as in electrode materials for
supercapacitors and as solid state hydrogen stores. The attractive properties of porous
carbons include, ready abundance, chemical and thermal stability, ease of processability
and low framework density. Activated carbons, which are perhaps the most explored
class of porous carbons, have been traditionally employed as catalyst supports or
adsorbents , but lately they are increasingly being used or finding potential application
in the fabrication of supercapacitors and as hydrogen storage materials. This manuscript
presents the state-of-the-art with respect to the preparation of activated carbons, with
emphasis on the more interesting recent developments that allow better control or
maximization of porosity, the use of cheap and readily available precursors and tailoring
of morphology. This review will show that the renewed interest in the synthesis of
activated carbons is matched by intensive investigations into their use in supercapacitors,
where they remain the electrode materials of choice. We will also show that activated
carbons have been extensively studied as hydrogen storage materials and remain a
strong candidate in the search for porous materials that may enable the so-called
Hydrogen Economy, wherein hydrogen is used as an energy carrier. The use of activated
carbons as energy materials has in the recent past and is currently experiencing rapid
growth, and this review aims to present the more significant advances.
