Two major challenges are particularly important for current research in the catalytic materials synthesis: preparation of finely divided particles and control of their shape. In this work we used non aqueous solvents to prepare catalytic materials containing transition metals oxides (Ti, Mn, Zr). Three techniques were applied to prepare TiO2-based solids. Reactions in molten alkali metal nitrates doped with different anions offered good control of textural properties and of the nature of exposed facets of nanocrystalline particles. Synthesis in molten ammonium nitrate stabilized with organic nitrogen-containing compounds provided TiO2 solids with variable size and shape as a function of stabilizer used. The reflux treatment in polar organic...
