  A novel intermittent microwave assisted method was developed for   surface impregnation and electrical

  properties improvement of decorated activated carbon (DAC), from   commercially available activated

  carbon (AC) and Vulcan carbon (VC). These materials were   characterized by UV-visible

  spectroscopy, Raman spectroscopy, X-ray diffraction (XRD),   Brunauer–Emmett–Teller (BET),

  scanning electron microscopy (SEM) and electrical conductivity.   The UV absorption peak in carbon

  materials is related to electronic transitions between the   bonding and antibonding π orbital. Raman

  spectroscopy and XRD results showed that the higher disorder of   amorphous carbon phase arose in

  DAC, when compared to typical AC. Results from BET analysis had   relatively high surface area of


  /g and total pore size volume of 0.524 m3

  /g for DAC. SEM analysis revealed that undefined

  structure of activated carbon material (~1-3 µm in size) breakage   into ~ 100 nm in size over this

  Vulcan carbon material (~60nm in size) was decorated. From the   electrical conductivity (σ) study, the

  value of σ followed the tendency DAC < VC < AC and   increased almost with pressure. High surface

  area and high conductivity decorated carbon nano structures could   be used as candidate hosts for metal

  electrocatalysts for fuel cell applications.
