Fabrication of N-Doped Highly Ordered Mesoporous Polymers and Carbons

Abstract

N-doped highly ordered mesoporous carbons are synthesized via a one-step organic-organic evaporation induced self-assembly method by using phenol, formaldehyde and m-aminophenol as carbon and nitrogen sources and triblock copolymer as a structure-directing agent. The frameworks are constituted by polymer and carbon upon calcination at 350 degrees C and 900 degrees C, respectively, and N incorporates into the frameworks (0.2-1.6% in molar ratio). N-doped mesoporous carbons have high surface areas (approximately 1200 m2/g) and large pore volumes (approximately 0.65 cm3/g). Various mesostructures (p6mm and Im3m) can be obtained by simply tuning the ratio of phenol to triblock copolymer in the synthesis. With the increase of the initial amount of m-aminophenol, the graphitizing degree of mesoporous carbon increases.
