An Ordered Mesoporous Aluminosilicate Oxynitride Template to Prepare N-Incorporated\nOrdered Mesoporous Carbon

Abstract

The synthesis and characterization of amorphous N-incorporated carbon materials, with ordered mesoporous\nstructure, using mesoporous aluminosilicate oxynitride (OMASON) as a solid template for the first time is\nreported. The use of furfuryl alcohol (FA) as carbon precursor generates the N-incorporated mesoporous\ncarbon material with nitrogen contents of ∼1.4−3.1 wt %. The nitrogen-containing groups existing in the\nOMASON template participate in the reactions during the carbonization process of polymerized FA/template\ncomposite, resulting in the formation of nitrogen-containing groups in the resulting mesoporous N-incorporated\ncarbon materials. The nitrogen contents of the obtainable mesoporous carbon materials evidently decrease\nwith increasing carbonization temperatures from 700 to 900 °C. Oppositely, the textural properties of\nmesoporous N-incorporated carbon materials are almost independent of the carbonization temperatures. All\nN-incorporated mesoporous carbon material have a high specific surface area (∼1600 m²/g) and high mesopore\nvolume (∼1.6 cm³/g) and a uniform mesopore size distribution. And the morphologies of the N-incorporated\nmesoporous carbon materials also derive from that of the OMASON template.
