This research master's degree project could be followed by a PhD
Work package:
The G group of LCC (part at Castres) develops greener
catalytic methods focused on organic solvent-free
processes [1] and/or supported catalysts. Recently,
polyoxometalates (POMs) ionically grafted on Merrifield
resins [2] or functionalized nanosilica beads [3-5]
exhibited catalytic properties towards (ep)oxidation. The
beads have been also used to replace one reagent [4]. The
aim of this project is to extend the nature of
functionalizations on Stöber-nano silica beads not only to
graft catalysts (POMs or tin clusters) for oxidative
transformation of natural substrates but also to use those
beads to replace reagents and/or to mimick solvents.
The objects will be fully characterized by several techniques present in Castres or Toulouse. All the
synthetic and catalytic work will be done in Castres.
