Ti(n)O(2n−1) Suboxide Phases in TiO(2)/C Nanocomposites Engineered by Non-hydrolytic Sol–Gel with Enhanced Electrocatalytic Properties

We report a non-hydrolytic sol-gel (NHSG) route to engineer original mesoporous Ti(n)O(2n−1)@TiO(2)/C nanocomposites. The synthetic approach is straightforward, solvent-free, additive-free, and meets the challenge of atom economy, as it merely involves TiCl(4) and THF in stoichiometric amounts. We f...

description We report a non-hydrolytic sol-gel (NHSG) route to engineer original mesoporous Ti(n)O(2n−1)@TiO(2)/C nanocomposites. The synthetic approach is straightforward, solvent-free, additive-free, and meets the challenge of atom economy, as it merely involves TiCl(4) and THF in stoichiometric amounts. We found that these nanocomposites present enhanced electrocatalytic properties towards the oxygen reduction reaction (ORR) in 0.1 M KOH. We believe that these preliminary results will open a window of opportunity for the design of metal suboxides/carbon nanocomposites through NHSG routes.
