Acetic Anhydride as an Oxygen Donor in the Non‐Hydrolytic Sol–Gel Synthesis of Mesoporous TiO2 with High Electrochemical Lithium Storage Performances

“…Among the various NHSG routes described in the literature, two main routes have proven particularly successful: 1) the so‐called benzyl alcohol route, based on the reaction of metal chloride or alkoxide precursors with benzyl alcohol acting as the solvent and oxygen donor and 2) the alkyl halide elimination route, based on the reaction of metal or silicon chlorides with alkoxide or ether oxygen donors. The benzyl alcohol route has mainly been used in the preparation of crystalline metal oxide nanoparticles, whereas the alkyl halide elimination route has been used both for the preparation of oxide nanoparticles (in the presence of capping agents or in dilute conditions) and for the synthesis of non‐ordered mesoporous oxides or mixed oxides …”

Lithium insertion properties of mesoporous nanocrystalline TiO2 and TiO2–V2O5 microspheres prepared by non-hydrolytic sol–gel

“…Over the last 25 years, several alternative non-hydrolytic sol-gel (NHSG) routes have emerged, aiming at solving the issues met in conventional sol-gel chemistry by a drastic change of reactions and reaction medium [1][2][3][4].…”

Matching the organic and inorganic counterparts during nucleation and growth of copper-based nanoparticles – in situ spectroscopic studies

“…[2][3][4][5][6] Specially for metal oxides, the advancement has been made possible due to the understanding that solvents are not only reaction medium but may also be an oxygen source and act as stabilizing agent. That knowledge has been gained by studying the organic compounds forming during synthesis.…”
