The Chevrel phase chalcogenides have a general formula of MxMo6S8 and well-defined molecular structure (M=transition metal). The Mo6S8 are molecular clusters that have Mo6 octahedral surrounded by S8 cubes, with S atoms lie at each face of the Mo6 octahedron. These clusters interconnect and form 3-dimensional channels that are available for hosting metal cations. This leads to designer chalcogenides with well-defined but tunable structural, electronic and catalytic properties, which are not easily attainable in other electrocatalyst materials. We will discuss the applications of this unique family of materials for electrocatalysis applications, including Li-S batteries and hydrogen peroxide synthesis.
