Abstract
In situ resistivity (formula presented) and thermoelectric power (S) have been used to study the nature of the adsorption of hydrogen in bundles of single-walled carbon nanotubes for (formula presented) pressure (formula presented) atm and temperatures (formula presented) Isothermal plots of S vs (formula presented) are found to exhibit linear behavior as a function of gas coverage, consistent with a physisorption process. Studies of S, (formula presented) at (formula presented) as a function of pressure exhibit a plateau at a pressure (formula presented) Torr, the same pressure where the H wt. % measurements suggest the highest binding energy sites are being saturated. The effects of (formula presented) exposure at 500 K on the thermoelectric transport properties are fully reversible.
