In this paper, three-dimensional bicontinuous porous graphite (3Dbp-graphite) with well-developed graphite structure is generated by dealloying in metallic melt at 1073 K in the low temperature region for synthesizing graphite. The N2 adsorption-desorption isotherm curves of 3Dbp-graphite show that the porous structure essentially consists of meso-macro pores. Its specific surface area and pore volume are 184.8 m2 g-1 and 0.84 cm3 g-1, respectively. These values are larger than the corresponding values of commercial acetylene black, which is widely used for energy devices. Both X-ray diffraction and the Raman spectra indicate that 3Dbp-graphite becomes more ordered when the graphitization process >2273 K. However, the specific surface area and total pore volume did not considerably decrease, indicating that porous graphite with extremely high electron conductivity and durability can be obtained by optimizing the dealloying and the following activation processes.
