Résumé en anglais

The synthesis of silicon micro- and nanoparticles is a central topic in the field of material chemistry. This material is particularly well suited for many different applications, from the realization of luminescent labels for in vitro and in vivo imaging 1 to the production of cathodes for lithium batteries 2. Recently, it has been reported that sub-micrometer Si particles are ideal for the production of optical and near-infrared metamaterials3. Today, the production of silicon particles is mainly addressed via soft chemistry routes, such as the reduction of silicon tetrachloride with strong reducing agents 4,5. These strategies typically yield low quantities of small silicon particles, and tedious post-synthesis purification steps are required to remove the by-products. These processes are not suitable for the continuous synthesis of Si particles in large quantities, and their scale-up from laboratory to industrial production is impaired. In this oral communication, we propose a novel strategy for the production of large silicon beads, using supercritical fluids.
