Oxide nanomaterials by non-hydrolytic sol-gel process
T
he non-hydrolytic sol-gel process involves the reaction in
non-aqueous media of several precursors (from transition
metals, post-transition metals or metalloids) with organic
oxygen donors instead of water. The reaction of chloride
precursors with an ether or an alkoxide at 80 up to 150°C
has provided useful alternatives to conventional sol-gel
routes for the design of oxide and mixed oxide materials.
This preparation can lead to interesting morphologies
(figure 1) and crystallinities. These nanomaterials have been
successfully used as heterogeneous catalyst, as well as energy
materials. In this presentation, I will focus on recent results
concerning other non-hydrolytic routes involving for instance
ester elimination (Figure 2), or original.
