Abstract

Hydrolysis of TiCl₄ in a diether-functionalized imidazolium ionic liquid (IL), namely 1-methyl-3-[2-(2-methoxy(ethoxy)ethyl]imidazolium methane sulfonate (M(MEE)I⋯CH₃SO₃), results in a heterostructured organic/inorganic and sponge-like porous TiO₂ material. The thermal treatment (300 ⋯C) followed by calcination (500 ⋯C) affords highly porous TiO₂. The characterization of the obtained samples (with and without IL, before and after calcination) by XRD, SEM, and TEM reveals TiO₂ anatase crystalline phases and irregular-shaped particles with different porous structures. These hierarchical-structured mesoporous TiO₂ nanomaterials were employed as efficient photocatalysts in the water-splitting process, yielding up to 1304 μmol g^-1 on hydrogen production.
