We prepared ordered porous carbons (PCs) by using a replication method that had well-organized mesoporous silica as a template with various carbonization temperatures in order to investigate the possibility of energy storage materials. The microstructure and morphologies of the samples are characterized by XRD, TEM, and FT-Raman spectroscopy. N{sub 2} adsorption isotherms are analyzed by the t-plot method, as well as the BET and the H-K method in order to characterize the specific surface area, pore volume, and pore size distribution of the samples, respectively. The capacity of the hydrogen adsorption of the samples is evaluated by BEL-HP at 77 K and 1 bar. From the results, we are able to confirm that the synthesis of the samples can be accurately governed by the carbonization temperature, which is one of the effective parameters for developing the textural properties of the carbon materials, which affects the behaviors of the hydrogen storage. - Graphical abstract: It is described that the considerable long-range ordering and the presence of mono-dimensional aligned channels between the two aligned nanorods of the porous framework from the SBA-15 was retained in the T-950 sample during the carbonization process. Highlights: > Ordered porous carbons (PCs) are synthesized with various carbonization temperatures by using a replication method. > Carbonization temperature plays an important role in shrinking the micropores during the carbonization process of PCs. > The textural and structural properties of the PCs are good parameters for enhancing the hydrogen storage capacity.
