Room temperature measurements of the 0.5-2.0 eV optical reflectance of carefully prepared pure stages 3,4,6 and the mixed stages (2,3) and (3,4) graphite-ferric chloride intercalation compound have been performed. The stages show metallic nature with a large contribution from the imaginary part of t
The amount of expansion on exfoliation is determined principally by the parent stage rather than the actual intercalate concentration. The amount of expansion increases with increasing stage of the parent compound before desorption. For the same parent stage, a higher concentration produces a larger
Stage-n Fe&GICs (n = 2,3) prepared in the standard two-zone method were oxidized galvanostatically in H,SO,. The electrode potential vs. electric quantity curves observed during the treatment and the X-ray powder patterns of the products showed clearly the intercalation of H,SO, into FeCI,-GICs and
Composition pressure isotherms of Hz and CO on graphite-ferric chloride rule out the possibility that the modified chemical or catalytic activity of metal intercalated graphite is the result of diffusion of reacting species between the layer planes. The catalytic activity for hydrocarbon synthesis d
