چکیده

In the present study, a type of graphitic mesoporous carbon (denoted as GMC) is synthesized and
its structural properties were characterized by nitrogen physisorption isotherms, transmission
electron microscopy and Raman spectroscopy. According to BET and BJH methods, the
specific surface area (SBET) and the average pore diameter of GMC are estimated to be
720 m2/g and 3.4 nm, respectively. Transmission electron microscopy shows the mesoporous
structure with stripe like patterns and less than 10 nm widths for GMC. Due to the large
surface area and high crystallinity of GMC, we used it to modify the glassy carbon electrode
(GCE). The electro catalytic behavior of modified electrode (GMC/GCE) was studied and
successfully compared with a conventional carbon mesoporous modified electrode (CMK-
3/GCE) and bare glassy carbon electrode (GCE). Cyclic voltammetry (CV) experiments
displayed the best electron efficiency for GMC/GCE.
