DESCRIPTION:Directed self-assembly of carbon nanostructures and metal nano
 particles into porous 3D structures\, provides unique opportunities to fab
 ricate monolithic\, highly-porous materials\, such as aerogels\, with well
 -controlled properties (e.g. microstructure\, porosity\, mechanical robust
 ness\, electro-thermal conductivity). Here\, we explore polymer-assisted n
 ano-structure assembly (carbon nanotubes\, graphene oxide\, metal nanopart
 icles)\, based on hydrothermal methods\, emulsion-templating and templatin
 g on sacrificial hard templates\, to produce nanocarbon and metal aerogels
  with fundamentally different microstructures. Different chemical methodol
 ogies (e.g. in-situ precipitation\, sublimation-deposition) are explored t
 o decorate the aerogel frameworks with catalyst and adsorbent nanoparticle
 s (anionic clays\, h-BN) in a uniform and consistent fashion. Supporting t
 hese functional nanoparticles within the structured aerogel frameworks res
 ults in significant improvements in their activity\, kinetics and regenera
 bility in important adsorption applications (adsorptive desulfurisation of
  hydrocarbons\, CO2 capture)1\,2 as well as in heterogeneous catalysis.3 I
 n order to exploit the benefits of these aerogels further\, the electrical
  conductivity of the cross-linked frameworks is utilised for direct resist
 ive heating\, enabling energy-efficient and very fast temperature control 
 and rapid thermal regeneration of spent adsorbents and catalysts.4
