“…5 that the superactivated carbon shows the capacity of 5 wt.% and is a better adsorbent of H 2 than the other conventional activated carbon, SWNT and GNF. The superactivated carbon is produced by the reaction of mesocarbon micro-beads (MCMB) with potassium hydroxide (KOH) and have a cage-like type of porosity [34]. Another superactivated carbon (30SPD, MSC30) was obtained from the reaction of coke with KOH [35], giving the same H 2 adsorption capacity of 5 wt.%.…”

“…To check this prediction, we took into consideration the experimental isotherms of methane and ethane adsorption on the activated carbon BPL, reported by Reich et al., and on two other carbons M-30 and M-38 reported by Nitta et al The BPL carbon adsorbent has been a popular adsorbent used in various adsorption processes, and therefore frequently studied in theoretical papers. Then, it should also be added that the data reported by Reich et al cover a wide range of temperatures which makes them a very attractive material for theoretical analysis.…”

Adsorption on a heterogeneous surface of flexible molecules composed of a number of mers, like n-alkanes for instance, is strongly affected by topography of surface adsorption sites. Therefore, fitting to experimental adsorption isotherms, theoretical expressions developed for multisite-occupancy adsorption on heterogeneous surfaces characterized by random and patchwise topography should make it possible to distinguish whether a studied solid surface is characterized by random or by patchwise topography. For certain fundamental but also practical reasons, we took into consideration carbonaceous adsorbents. Following the general approach to multisite-occupancy adsorption published recently by Rudziński and Everett, we have developed here a generalized form of the Dubinin−Astakhov isotherm equation, taking into account surface topography and the interactions between the adsorbed molecules. The developed isotherm equation has been used successfully by us to study the nature of surface topography of a number of carbonaceous adsorbents.

Microbead and nanophase carbon materials attract many researchers due to their unique applications, [1] which include high-density and high-strength carbon artifacts, [2] super-active carbon beads of high surface area, [3] lithium storage, [4a] lithium battery anodes, [4b-d] spherical packing materials for HPLC, [5] hydrogen storage applications, [6] and catalysis. [7] Much attention has focused on the preparation (precursors and methods) and properties of these carbon materials, because their applications significantly depend on the shape and size of the particles.Carbon nitrides are of current interest due to their novel mechanical, optical, and tribological properties, including low density, extreme hardness, surface roughness, wear resistance, chemical inertness, and biocompatibility.[8] These superhard diamondlike materials promise a variety of technological and biological applications. For example, they are used as biocompatible coatings on biomedical implants, [8][9] battery electrodes, [10] catalytic supports, [11] gas separation systems, [12] electronic materials, [13] and humidity and gas sensors.[14]Unlike carbon-based materials, applications of carbon nitrides are not only governed by the texture and size of the particles [13] but also by the relative nitrogen content. As a consequence, an extensive effort has focused on the discovery of precursors along with the appropriate methods to increase the nitrogen content in carbon nitrides.There is very little literature on the preparation of carbon nanospheres and nitrogen-rich carbon nitrides (> 60 wt % N). Gillan reported preparations of carbon nitrides C 3 N 4 (60.9 wt % N) and C 3 N 5 (66.0 wt % N) and graphitic carbon using high-nitrogen 2,4,6-tri(azido)-1,3,5-triazine as the pre-
