ملخص المقالة :
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.
