N2 - Triazine-based porous carbon materials (TPCs) have been synthesized via cyclotrimerization of aromatic tetranitriles and in situ carbonization. The resulting TPCs have high surface area (above 1200 m2 g-1), large pore volume (above 1.4 cm3 g-1), and hierarchical pore structures with micropores (0.63-1.24 nm) and mesopores (2.4-20 nm). Gas adsorption experiments demonstrate their promising hydrogen uptake capacity, up to 2.34 wt% at 77 K and 1.0 bar, due to the hierarchical porosity that facilitates the diffusion and adsorption of gas molecules.
