Nitrogen-doped mesoporous graphene (NMG) with interpenetrating porous network was successfully fabricated by hydrothermal process of graphite oxide (GO) and self-assembled triblock copolymer template (Pluronic P123) in the presence of ammonium hydroxide as a nitrogen source. The structure, morphology, chemical components, and porous nature of the obtained NMGs were characterized by X-ray diffraction, scanning electron microscopy, energy dispersive spectrometry, and N2 adsorption-desorption measurements, respectively. The fabricated NMGs have high BET specific surface area (~ 1107 m2 g-1), bottle neck like pores with three-dimensional interconnected network, and average pore size with 4.9 ~ 6.3 nm. To preliminary test the performance as a absorbent for volatile organic compounds (VOCs), absorption test using formaldehyde was evaluated in comparison with undoped mesoporous graphene (MG).
