Synthesis of nitrogen-doped mesoporous carbon using templating technique

Abstract

N-doped mesoporous carbon with three dimensional and cage type pore structure has been synthesized for the first time via templating process using three dimensional cage type mesoporous silica (KIT-6) and aniline as the template and the nitrogen source, respectively. Ammonium peroxy sulfate, NH4S2O8, was used to polymerize the aniline molecules. The obtained material has been unambiguously characterized by various sophisticated techniques such as powder X-ray diffraction, nitrogen adsorption measurement, CHN analysis, and x-ray photoelectron spectroscopy. The XRD results revealed that the material exhibits a well ordered three dimensional mesoporous structure. Nitrogen adsorption data indicates that the material possesses very high surface area and pore volume.
