Copper intercalated

The HF-SbFs system is known to be a superacid H34). The possible relevance of this to the intercalation process was pointed out by Vogel V12), who first reported on the extremely high electrical conductivity of graphite-SbFj measured normal to the crystallographic c-axis. The measured conductivity was approximately 40 times that of pristine graphite, and 50% greater than that of pure copper. Other workers... 

A great deal of excitement has been generated by the assertion that some intercalation compounds of graphite possess a conductivity greater than that of copper (VIO, F13, Til). Much of this work was based upon earlier researches by Ubbelohde, who found that the a-axis conductivity of the semi-metal graphite increases, and develops a me-...

The metastable spinel form of TiS2, which has cubic close-packing of the sulfide ions, was similarly formed by the deintercalation of copper from CuTi2S4. ° This cubic structure can also be reversibly intercalated with lithium, although the diffusion coefficient is not as high as in the layered form. 

NEtH3 and NPhH3) are isomorphous with the corresponding copper(II) complexes, which are known to have chloride-bridged sheets intercalated with the organic cations. 

Lead and mercury are deposited as micron-sized clusters, predominantly at intercrystallite boundaries [105] so does lithium from the polyethylene oxide solid electrolyte. What is more, Li intercalates into the sp2-carbon [22, 138], Thus, observations on the Li intercalation and deintercalation enable one to detect non-diamond carbon on the diamond film surface. Copper is difficult to plate on diamond [139], There is indirect evidence that Cu electrodeposition, whose early stages proceed as underpotential deposition, also involves the intercrystallite boundaries [140], We note that diamond electrodes seem to be an appropriate tool for use in the well-known electroanalytical method of detection of traces of metal ions in solutions by their cathodic accumulation followed by anodic stripping. The same holds for anodic deposition, e.g. of, Pb as PbCh with subsequent cathodic reduction [141, 142], Figure 30 shows the voltammograms of anodic dissolution of Cd and Pb cathodically predeposited from their salt mixtures on diamond and glassy carbon electrodes. We see that the dissolution peaks are clearly resolved. The detection limit for Zn, Cd, and Pb is as low as a few ppb [143]. 

Chevrel phase compounds, AxMo6Ch8 (Ch = S, Se or Te), may also be considered as intercalation compounds. Mo6S8 can be prepared by acid-leaching copper from CuxMo6S8.

Graphite intercalation compounds have received widespread interest for two main reasons. First, intercalation results in compounds that have metallic conductivity. The electrical conductivity can approach that of copper metal and is highly anisotropic ratios of the conductivity in-plane to that along the c axis can be six orders of magiutude at room temperature. Secondly, graphite is a unique host lattice in that intercalation compounds can be formed with either electron donors or electron acceptors as guest species. 

Oxides containing bismuth oxygen atom double layers include the bismuth calcium copper oxide series of superconductors exemplified by Bi2Sr2CaCu20g (Bi-2212) and the beta phase oxide ion conductors based on the composition Sr Big j 0(2 j)/2. While the details of these two stmcture types are quite different, they have the common feature of containing BiMT double layers that are only weakly bonded. In Bi-2212, the bismuth atoms are four + one coordinated by oxygen atoms whereas, in Srj Bi9 j 0(2 j)/2 they are three + one coordinated and form square and hexagonal layers of Bi-O bonds. Both classes of compounds and be intercalated by iodine atoms that are inserted between the Bi-O double layers.
