Nanoporous carbon (NPC) is prepared by direct carbonization of Al-based porous coordination polymers (Al-PCP). By applying the appropriate carbonization temperature, both high surface area and large pore volume are realized for the first time. Our NPC shows much higher porosity than other carbon materials (such as activated carbons and mesoporous carbons). This new type of carbon material exhibits superior sensing capabilities toward toxic aromatic substances.

Here, we report preparation of microporous carbon fibers through carbonization of an Al-based porous coordination polymer (Al-PCP) with furfuryl alcohol (FA) at 1000 °C under an inert gas atmosphere. During the carbonization process, the Al species are aggregated to form γ-alumina nanoparticles. After the carbonization, the γ-alumina nanoparticles (from 2 to 10 nm) are distributed over the entire area. By chemical treatment with HF, the γ-alumina nanoparticles can be easily removed to obtain pure microporous carbon. Interestingly, the fibrous morphology of the original Al-PCP is successfully retained after the carbonization process. The effect of the loading amount of FA into the porous networks of Al-PCP on properties of the obtained microporous carbon is carefully examined. From the N2 adsorption−desorption isotherms, an increase in the BET surface area upon increasing the loading amount of FA is observed. The maximum surface area and pore volume of the obtained microporous carbon reach 513 m2/g and 0.844 cc/g, respectively.

A novel highly ordered three-dimensional mesoporous carbon-nitride-based hybrid material (MCN-2) with very high surface area, pore volume, and a possible cage type porous structure has been prepared using three-dimensional cage type mesoporous silica, SBA-16, as a template through a simple polymerization reaction between ethylenediamine and carbon tetrachloride. The material has been unambiguously characterized by various sophisticated techniques such as XRD, nitrogen adsorption, HRTEM, EELS, XPS, 13C DD-MAS, and FT-IR spectroscopy. The XD result reveals that MCN-2 possesses three-dimensional structure with a possible Im3m space group. The specific surface area and pore volume of MCN-2 are significantly higher as compared to those of the template and MCN-1. Because of the excellent textural characteristic and three-dimensional porous structure, we believe that the MCN-2 could offer great potential for the applications such as catalysis and adsorption.
