A synthetic method to produce mesoporous carbons with tunable textural properties and ordered pore structure has been developed by changing sucrose to water ratio. The specific surface area of 1437 m2/g with pore volume of 1.4 cm3/g and porosity of mesopores centered at around 4.4 nm are achieved by tuning the concentration of filling amount into mesoporous silica. The mesoporous carbon exhibits hexagonal rod-like morphology (a diameter of ~1.2 m), which confirms that the replication process is highly successful. It is demonstrated that the prepared mesoporous carbon exhibits much higher current density and superior performance as compared to conventional activated charcoal.

Nitrogen-doped ordered mesoporous carbon has been synthesized and used to confine LiBH4 to improve its dehydrogenation properties. The carbon has a high BET specific surface up to 448.25 m2/g with pore size centered at 1.2 and 4.1 nm. The effects of ball milling time and speed on de-hydrogenation were investigated. The onset hydrogen desorption temperature of LiBH4 is reduced to 100 °C by addition 40 wt% carbon, and it can release hydrogen of 8.3 wt% at 380 °C. Furthermore, cyclic dehydrogenation is studiedto estimate the stability of the samples in the present work.

Nitrogen hybrid ordered mesoporous carbons (N-OMC) were prepared by the soft-template method with melamine-phenol-formaldehyde resoles (MPF) as the precursors and triblock copolymer F127 as a soft-template. FT-IR spectra analysis demonstrated that nitrogen was incorporated into the mesoporous carbons with C-N covalent bonds. The effect of molar ratio of phenol to melamine on the pore structure and textural properties was discussed by small angle X-ray scattering, nitrogen adsorption measurements, and transmission electron microscopy. The results show that the degree of pore order decreases with the increasing of nitrogen content. The N-OMC with 3.39 wt% nitrogen has the highest specific surface areas (573m2/g) and best ordered mesostructure.
