A novel nitrogen-doped mesoporous carbon with well-ordered two-dimensional (2D) structure has been successfully prepared for the first time using aniline as a source for both carbon and nitrogen, and SBA-15 as a template. The above material has been unambiguously characterized by various sophisticated techniques such as XRD, HRTEM, XPS, and nitrogen adsorption. The obtained material possesses very high surface area, pore volume, and uniform pore size distribution. The XPS and CHN analysis revealed that nitrogen atom is successfully doped on the mesoporous carbon walls.
