Adsorption and melting of hydrogen in potassium-intercalated graphite
Volumetric adsorption and quasielastic neutron scattering are used to study the diffusion and thermodynamics of sorbed H2 in the graphite intercalation compound KC24. A sorption enthalpy of 8.5 kJ/mol at zero coverage is determined from H2 adsorption isotherms. From measurements of total elastic-neutron-scattering intensity as a function of temperature, a melting transition of the H2 adsorbate ...
متن کاملPhoto- and thermionic emission from potassium-intercalated carbon nanotube arrays
Carbon nanotubes CNTs are promising candidates to create new thermionicand photoemission materials. Intercalation of CNTs with alkali metals, such as potassium, greatly reduces their work functions, and the low electron scattering rates of small-diameter CNTs offer the possibility of efficient photoemission. This work uses a Nd:YAG YAG denotes yttrium aluminum garnet laser to irradiate singlean...
متن کاملPotassium-intercalated H2Pc films: alkali-induced electronic and geometrical modifications.
X-ray spectroscopy studies of potassium intercalated metal-free phthalocyanine multilayers adsorbed on Al(110) have been undertaken. Photoelectron spectroscopy measurements show the presence of several charge states of the molecules upon K intercalation, due to a charge transfer from the alkali. In addition, the comparison of valence band photoemission spectra with the density functional theory...
متن کاملPotassium 2-(N-hydroxycarbamoyl)acetate monohydrate
The crystal structure of the title compound, K(+)·C(3)H(4)NO(4) (-)·H(2)O, consists of potassium cations, monoanions of 2-carboxy-acetohydroxamic acid [namely 2-(N-hydroxy-carbamo-yl)acetate] and solvent water mol-ecules. The elements of the structure are united in a three-dimensional network by numerous K⋯O coordinate bonds and O-H⋯O and N-H⋯O hydrogen bonds. The coordination sphere of the K(+...
متن کاملHydrogen diffusion in potassium intercalated graphite studied by quasielastic neutron scattering.
The graphite intercalation compound KC(24) adsorbs hydrogen gas at low temperatures up to a maximum stoichiometry of KC(24)(H(2))(2), with a differential enthalpy of adsorption of approximately -9 kJ mol(-1). The hydrogen molecules and potassium atoms form a two-dimensional condensed phase between the graphite layers. Steric barriers and strong adsorption potentials are expected to strongly hin...
