The H2 isotherms on graphite, CsFeCIs and ClOFeCI, are identical but when activated, &FeCl, shows higher absorption. This suggests that the metallic Fe produced on activation of CsFeCll in Hz at 375Β°C is on the surface and is not intercalated. The activated intercalation compound, CsFer&, catalyzes

β¦ Synopsis
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 develops by the thermal decomposition of FeCl, to FeCl, + Cl, and is caused only by that fraction that diffuses out of the graphite

The experimental techniques for intercalating highly oriented pyrolytic graphite crystals and large size graphite flakes with metal halides are well known and easily carried out. However, as the size of the graphite flakes decrease below 5 microns the conditions for intercalation become more difficu
The self-radiolysis of mixtures of CO and tritium (3H2) has been studied at pressures of 0.25 to 1 .O atmospheres, temperatures of -198" to 4-lOO"C, and in the presence of added HzO or COZ. The products of decomposition are COZ, 3H20, C3H4, G3H4, and a white polymer believed to be polyformaldehyde.
