Resumen:
Porous carbons, owing to their surface properties and stability, are very attractive for applications in various areas, such as adsorption, purification of water, catalysis, electrochemistry, and others. Recently, the successful synthesis of mesostructured mesoporous carbons (MMCs) was discovered, in which ordered mesoporous silicas were employed as templates. Compared to materials with disordered pore systems, MMCs allow precise control over their pore dimensions and arrangement, which is vital for applications requiring size and shape selectivity, hierarchical material organization, and pore accessibility. The use of ordered mesoporous templates permits obtaining carbons with high specific surface areas (ca. 2000 m2/g) and pore volumes (ca. 1.5 cm3/g). In particular, using furfuryl alcohol as a carbonsource and SBA-15 aluminosilicate as a template, Ryoo and co-workers synthesized an ordered mesoporous carbon named CMK-3, which consists of two-dimensional (2D) hexagonal arrays of carbon nanorods. Pore sizes of previously synthesized CMK-3 carbons were verified using techniques such as XRD and TEM . However, complete gas adsorption behavior including pore size/textural analysis of these carbons is necessary in order to fully understand the properties and pore structure of these nanostructured materials.
