Nanocarbons other than CNTs and graphene often exhibit similar surface chemistry and can be hybridized in a similar fashion. For example, single-walled carbon nanohorns (SWCNHs) have been oxidized via heat treatment in air atmosphere followed by immersion in a solution containing H2PtCl6. The Pt ions adsorbed to the oxidized SWCNHs and were then reduced via addition of sodium citrate to form Pt NPs [150],... 

In many cases the potential application of single-walled carbon nanotubes is associated with solubility of this nanomaterial in different solvents. Unfortunately, nanotubes are poorly soluble in the most of organic solvents and are insoluble in water, and this fact especially hinders biological using SWNT. Weak solubility of SWNT is a result of substantial van der Waals attractions between nanotubes aggregated in bundles. To solve nanotubes in water without any covalent functionalization, a surfactant would be added into aqueous solution, and then this mixture is suspended by sonication. It is supposed that the sound wave splits bundles in aqueous solution. A surfactant in suspension adsorbed onto the nanotube surfaces precludes aggregation of nanotubes in bundles.

Active carbon has exceptional adsorption properties because of its high surface area, its developed porosity, the wide variety of functional groups in its surface, and its relatively high mechanical strength [77-79], As a result, active carbons are usually applied in numerous industrial procedures for the elimination of impurities from gases and liquids [77], In this section, two examples of carbon-related adsorbents, that is, a Fisher powdered active carbon and a single-walled carbon nanotube (SWCNT), are presented [80],... 

On the base of this approach thermodynamics of hydrogen absorbed outside and inside the (10,10) and the (20,20) single-wall carbon nanotubes with diameters 13.56 A and 27.13 A, respectively, was calculated. The dependencies of free energy F and thermodynamical potential H on applied pressure P and temperature T were calculated. The dependencies of content of hydrogen adsorbed on nanotubes m(P,T) surface on pressure and temperature were calculated from these data. For the first time the dependencies of m(P,T) with accounting of quantum effects and van der Waals forces were calculated.

The discovery of new materials such as nanoparticles and nanotubes has led to their use in electrochemical sensors in combination with ferrocene mediators and redox enzymes. Davis and co-workers modified single-wall carbon nanotubes (SWCNTs) by adsorbing glucose oxidase to them and then used a soluble ferrocene derivative as a...
