synthesis of Intercalation Compounds of molybdenum disulfide with nitrogen containing organic molecules and study of their microstructure
Russian Chemical Bulletin, 2004Co-Authors: Alexandre S Golub, V I Zaikovskii, Natalia D Lenenko, M Danot, Yu. N. NovikovAbstract:Reactions of single-layer dispersions of molybdenum disulfide with 2,2′-bipyridyl, para-phenylenediamine, and hexamethylenetetramine afford Intercalation Compounds consisting of alternating MoS2 layers and layers formed by organic molecules. The structures of the Intercalation Compounds were characterized by X-ray powder diffraction and electron microscopy data. The influence of pH on the composition of resulting Compounds and the packing of the intercalant was examined.

single layer dispersions of transition metal dichalcogenides in the synthesis of Intercalation Compounds
Russian Chemical Reviews, 2003Co-Authors: Alexander S Golub, Ya V Zubavichus, Yu L Slovokhotov, Yu. N. NovikovAbstract:Chemical methods for the exfoliation of transition metal dichalcogenides in a liquid medium to give single-layer dispersions containing quasi-two-dimensional layers of these Compounds are surveyed. Data on the structure of dispersions and their use in the synthesis of various types of heterolayered Intercalation Compounds are discussed and described systematically. Structural features, the electronic structure and the physicochemical properties of the resulting Intercalation Compounds are considered. The potential of this method of synthesis is compared with that of traditional solid-state methods for the Intercalation of layered crystals. The bibliography includes 192 references.

Model for constitution of graphite Intercalation Compounds
Synthetic Metals, 1994Co-Authors: Vladimir Z. MordkovichAbstract:Abstract A model for the constitution of graphite Intercalation Compounds has been proposed. The model is based on the assumption that intercalant particles may be considered as elastic balls squeezed by elastic graphitic networks. Stability limits (minimum pressure of existence) and compressibilities were calculated for a large number of donor Intercalation Compounds. Agreement with experimental data is excellent. Stability limits of some non-discovered Compounds and several compressibilities have been predicted. In particular, the calculated compressibility of recently discovered C2Na is 11 × 10−12 Pa−1. The possibility of applying this model to acceptor Compounds and higher stage Compounds has been discussed.

use of amine electride chemistry to prepare molybdenum disulfide Intercalation Compounds
RSC Advances, 2014Co-Authors: Amila Udayanga Liyanage, Michael M LernerAbstract:Electride solutions, formed by dissolution of Na(m) in ethylenediamine (en), are used to generate MoS2 Intercalation Compounds. Two new Intercalation Compounds were obtained, labeled α and β phases, containing both Na and en as intercalate and cointercalate respectively. The Intercalation reaction proceeds via formation of a kinetic product, the β phase, and subsequent generation of a stable thermodynamic product, the α phase. The β and α phases have interlayer distances, dIC, of 1.19 and 0.97 nm, respectively, which are ascribed to a perpendicular or parallel orientation of en within the intercalate galleries. Product compositions, morphologies and spectrochemical features are obtained from thermogravimetry, SEM and Raman measurement. Electrochemical reduction of MoS2 in an en-based electrolyte is investigated, but does not show the same Intercalation reactions. The chemistry observed is compared with that previously reported for this and other MS2 hosts, and with graphite Intercalation.

Graphite Intercalation Compounds
Reference Module in Materials Science and Materials Engineering, 2016Co-Authors: Deborah D.l. ChungAbstract:Graphite Intercalation Compounds are a type of graphite Compounds. They are interstitial Compounds in which the foreign species (the intercalate) is included in the interplanar sites of the graphite crystal. They are classified into ionic Compounds (e.g., graphite–lithium and graphite–bromine) and covalent Compounds (e.g., graphite oxide). Intercalation can only occur in carbon materials that are strongly graphitic. Thus, carbon fibers that are not graphitic cannot be intercalated. Upon heating, an Intercalation compound expands along the c -axis, resulting in exfoliated graphite, which has a cellular structure. Upon compression, exfoliated graphite forms flexible graphite, due to the mechanical interlocking among the worms.
