“…The solid-state method is used earliest to synthesize MMSs, in which two metals and sulfur are first mixed together and then heated at high temperature under inert atmosphere or vacuum condition. [42][43][44][45][46][47] For the solid-state method, it usually needs high temperature (>500 °C) and long reaction time (usually several days). In addition, the solid-state strategy offers little control over the desirable size, morphology, and structure of obtained MMSs.…”

“…On the other hand, no metal deposition in the cathodes of Ni x Mo 6 S 8−y , Co x Mo 6 S 8−y , Fe x Mo 6 S 8−y , and Cr x Mo 6 S 8−y even after deep cycling resulted in improved cycling behavior. [43][44][45]47] However, their relatively low specific capacities (below 100 mA h g −1 ) and operating voltages (around 2 V vs Li/Li + ) have hindered their use as cathode materials in commercial cells. Conventional pathways for the synthesis of Chevrel phase materials require high temperature (≥1000 °C) and long time (usually several days).…”

Mixed metal sulfides (MMSs) have attracted increased attention as promising electrode materials for electrochemical energy storage and conversion systems including lithium‐ion batteries (LIBs), sodium‐ion batteries (SIBs), hybrid supercapacitors (HSCs), metal–air batteries (MABs), and water splitting. Compared with monometal sulfides, MMSs exhibit greatly enhanced electrochemical performance, which is largely originated from their higher electronic conductivity and richer redox reactions. In this review, recent progresses in the rational design and synthesis of diverse MMS‐based micro/nanostructures with controlled morphologies, sizes, and compositions for LIBs, SIBs, HSCs, MABs, and water splitting are summarized. In particular, nanostructuring, synthesis of nanocomposites with carbonaceous materials and fabrication of 3D MMS‐based electrodes are demonstrated to be three effective approaches for improving the electrochemical performance of MMS‐based electrode materials. Furthermore, some potential challenges as well as prospects are discussed to further advance the development of MMS‐based electrode materials for next‐generation electrochemical energy storage and conversion systems.

“…In their studies both transition-metals CPs were removed with aqueous electrolyte, and alkaline CPs with an organic one [81]. These results opened the way to the study of CPs as cathode materials for with lithium and organic electrolyte [82][83][84][85][86]. Thick [87] and thin-films [88,89] were also studied.…”

This chapter summarizes the important role played by Marcel Sergent in the discovery in the Rennes Laboratory of the Chevrel-Phases, which stimulated considerable interest in the international solid state chemistry community, because of their remarkable superconducting properties. After a brief general introduction to this topic the seminal discoveries associated with these phases between 1970 and 1990 are described. After their initial synthesis and structural determination was discovered, it was necessary to establish their critical superconducting transition temperature, the critical magnetic field and the critical current density in wires, single crystals, and thin films. More recently their applications as battery materials, in catalysis and their thermo-electric properties have been studied and are briefly described. These phases opened up the way not only to a rich solid state chemistry, but also to a rich solution chemistry, which complemented the classical field of transition metal carbonyl clusters. The basic cluster units of the Chevrel-Phases continue to be studied in the Rennes laboratory by the heirs of Marcel Sergent and more widely in the international community.

The underlying background and present development of methanol tolerant electrocatalysts, selective for the oxygen reduction reaction (ORR), are presented. These catalysts are essentially metal‐centered (ruthenium) clusters or cluster‐like compounds. These clusters, partially embedded in a chalcogenide matrix (e.g., selenium) constitute the active center for the electrochemical process ORR. On well‐defined cluster materials, as for example, the so‐called Chevrel phases, based on octahedron clusters [(Mo 2/3 Ru 1/3 ) 6 Se 8 ], the ORR electrochemical activity clearly indicated that this phenomenon can be selectively sustained with a four‐electron charge transfer (water formation). This is due to their electronic and geometric characteristics. Hence, clusters work as a pool of charges that can be engaged in a multi‐electron process. Therefore, this family of materials served as a model for the development of novel ones. In this respect, e.g., Ru x Se y ( x ≈ 2, y ≈ 1), tailored from chemical precursors in organic solvents, under mild conditions, shows a high dispersiveness in the nanoscale range. The metallic center shows similar electrochemical properties to those of well‐defined Chevrel phases, thus behaving as a cluster‐like material. The ability of the catalytic center to provide coordination chemistry for reactivity and selectivity via cluster, or cluster‐like compounds is discussed, as well as the trends in the synthesis and the results of tests in half‐cells and in direct methanol fuel cell systems.
