“…Variable temperature diffraction experiments revealed that the troilite phase transformed to monoclinic pyrrhotite of composition Fe 7 S 8 above 250 °C, as evidenced by peak shape analysis of specific reflections. This confirmed that the samples indeed consisted of troilite with an unusual stoichometry, and that NHSG chemistry provides facile access to small, well-defined hexagonal particles of this phase (Figure 6) [116]. …”

Low temperature methods have been applied to the synthesis of many advanced materials. Non-hydrolytic sol-gel (NHSG) processes offer an elegant route to stable and metastable phases at low temperatures. Excellent atomic level homogeneity gives access to polymorphs that are difficult or impossible to obtain by other methods. The NHSG approach is most commonly applied to the preparation of metal oxides, but can be easily extended to metal sulfides. Exploration of experimental variables allows control over product stoichiometry and crystal structure. This paper reviews the application of NHSG chemistry to the synthesis of negative thermal expansion oxides and selected metal sulfides.

“…The pattern of the film grown at 658 K (Figure 4(a)) reveals the formation of both Troilite-2H (FeS; JCPDS 00-037-0477) and Pyrite (FeS 2 ; JCPDS 00-042-1340). The FeS crystalline structure corresponds to hexagonal Troilite-2H [38][39][40] and the FeS 2 corresponds to cubic pyrite. [12,41,42] As the reaction temperature is increased to 768 K (Figure 4(b)), only Troilite is detected indicating that at these reaction temperatures its Downloaded by [University of Sherbrooke] at 01:30 13 April 2015 formation is favored.…”

2015): Synthesis of iron sulfide films through solid-gas reaction of iron with diethyl disulfide, Journal of Sulfur Chemistry, Iron sulfide films were synthesized by the solid-gas reaction of diethyl disulfide on iron foils in the temperature range of 658-768 K using a microbalance, where the film growth kinetics followed Deal-Grove behavior. Analysis of the films by X-ray photoelectron and Raman spectroscopies as well as X-ray diffraction and scanning electron microscopy analysis revealed the formation of combined FeS/FeS 2 (troilite/pyrite) films with a sheet-like morphology at low temperatures and only FeS (troilite) films with granular morphology at higher temperatures.

Functionalisation of Colloidal Transition Metal Sulphides Nanocrystals: A Fascinating and Challenging Playground for the Chemist

Abstract:Metal sulphides, and in particular transition metal sulphide colloids, are a broad, versatile and exciting class of inorganic compounds which deserve growing interest and attention ascribable to the functional properties that many of them display. With respect to their oxide homologues, however, they are characterised by noticeably different chemical, structural and hence functional features. Their potential applications span several fields, and in many of the foreseen applications (e.g., in bioimaging and related fields), the achievement of stable colloidal suspensions of metal sulphides is highly desirable or either an unavoidable requirement to be met. To this aim, robust functionalisation strategies should be devised, which however are, with respect to metal or metal oxides colloids, much more challenging. This has to be ascribed, inter alia, also to the still limited knowledge of the sulphides surface chemistry, particularly when comparing it to the better established, though multifaceted, oxide surface chemistry. A ground-breaking endeavour in this field is hence the detailed understanding of the nature of the complex surface chemistry of transition metal sulphides, which ideally requires an integrated experimental and modelling approach. In this review, an overview of the state-of-the-art on the existing examples of functionalisation of transition metal sulphides is provided, also by focusing on selected case studies, exemplifying the manifold nature of this class of binary inorganic compounds.
