Carbon adsorbents graphene

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],... [Pg.152]

The main difference between carbon nanotubes and high surface area graphite is the curvature of the graphene sheets and the cavity inside the tube. In microporous solids with capillaries which have a width not exceeding a few molecular diameters, the potential fields from opposite walls will overlap so that the attractive force which acts upon adsorbate molecules will be increased in comparison with that on a flat carbon surface [16]. This phenomenon is the main motivation for the investigation of the interaction of hydrogen with carbon nanotubes (Figure 5.14). [Pg.123]
