Abstract
A novel hierarchical nanotemplated carbon
monolithic rod (NTCM) was prepared using a novel facile
nanotemplating approach. The NTCM was obtained using
C60-fullerene modified silica gels as hard templates, which were
embedded in a phenolic resin containing a metal catalyst for
localized graphitization, followed by bulk carbonization, and
template and catalyst removal. TEM, SEM, and BET
measurements revealed that NTCM possessed an integrated
open hierarchical porous structure, with a trimodal pore
distribution. This porous material also possessed a high
mesopore volume and narrow mesopore size distribution.
During the course of carbonization, the C60 conjugated to aminated silica was partly decomposed, leading to the formation of
micropores. The Raman signature of NTCM was very similar to that of multiwalled carbon nanotubes as exemplified by three
major peaks as commonly observed for other carbon materials, i.e., the sp3
and sp2
carbon phases coexisted in the sample. Surface
area measurements were obtained using both nitrogen adsorption/desorption isotherms (BET) and with a methylene blue
binding assay, with BET results showing the NTCM material possessed an average specific surface area of 435 m2 g−1
, compared
to an area of 372 m2 g−1
obtained using the methylene blue assay. Electrochemical studies using NTCM modified glassy carbon
or boron doped diamond (BDD) electrodes displayed quasi-reversible oxidation/reduction with ferricyanide. In addition, the
BDD electrode modified with NTCM was able to detect hydrogen peroxide with a detection limit of below 300 nM, whereas the
pristine BDD electrode was not responsive to this target compound.
