Solid-state synthesis in sealed silica tube is one of the most popular methods for the production of inorganic ceramics. Nevertheless, the determination of the best synthesis conditions is a trial-and-error process that generally requires many experiments, varying temperature and duration time. In situ studies of the successive chemical reactions occurring during the synthesis of a polycrystalline sample by thermal analysis, diffraction and spectroscopy techniques can be powerful tools to determine the reaction pathways, allowing to reduce considerably the number of trials and to optimize the synthesis conditions [1]. On the other hand, the use of soft synthesis conditions is an alternative approach for the stabilization of new inorganic compounds that cannot be obtained by high temperature synthesis route commonly used in solid-state chemistry [2]. This was largely demonstrated in tungsten cluster halide chemistry with the discovery of large number of new inorganic compounds with low nuclearity [3].
This post-doctoral position focuses on the synthesis and characterization of new inorganic 3d transition metal sulfides for energy conversion (magnetocaloric, thermoelectric, photovoltaic …). The aim is to develop an innovative experimental approach combining low temperature synthesis and in situ studies by thermal analysis, diffraction and/or spectroscopy techniques in order to discover new compounds and to determine their crystal structures and potential as materials for energy conversion.
