“…[16] These structures can be realized by using organic templates followed by solvent extraction and/or calcination. [17][18][19] Thus, block copolymers can be used as templates in order to obtain highly crystalline, mesoporous TiO 2 without collapse of the mesostructure. [20] In general, colloidal latex particles present convenient templates for the synthesis of macroporous TiO 2 networks.…”

We synthesized well‐defined, crystalline TiO2 nanoparticles at room temperature by using spherical polyelectrolyte brush particles as a template. The template particles consist of a polystyrene core from which long chains of poly(styrene sodium sulfonate) are grafted. Tetraethylorthotitanate is hydrolyzed in the presence of brush particles leading to the formation of well‐dispersed TiO2 nanoparticles (d = 4∼12 nm). Wide‐angle X‐ray scattering demonstrates that anatase nanoparticles with high crystallinity have been generated at room temperature. The as‐prepared TiO2 nanocomposites present high photocatalytic activity for the degradation of Rhodamine B under UV irradiation. Finally, mesoporous TiO2 structures with defined pore size are formed after calcination.magnified image

“…For instance, Ulagappan and Rao successfully prepared 2D hexagonal mesoporous TiO 2 using neutral amine surfactants and Ti(OPr) 4 as a titanium source [11]. Froba et al attempted to use three different bidentate ligands (1,3-propanediol, 1,5-pentanediol and 2,4-pentanedione) to modify the reactivity of titanium tetraisopropoxide and obtain ordered mesostructured TiO 2 [12]. Niessen et al prepared Ti-based MCM-41 materials using (NH 4 ) 3 [Ti(O 2 )F 5 ] as a novel titanium source [13].…”

This review article summarizes recent developments in mesoporous titania materials, particularly in the fields of morphology control and applications. We first briefly introduce the history of mesoporous titania materials and then review several synthesis approaches. Currently, mesoporous titania nanoparticles (MTNs) have attracted much attention in various fields, such as medicine, catalysis, separation and optics. Compared with bulk mesoporous titania materials, which are above a micrometer in size, nanometer-sized MTNs have additional properties, such as fast mass transport, strong adhesion to substrates and good dispersion in solution. However, it has generally been known that the successful synthesis of MTNs is very difficult owing to the rapid hydrolysis of titanium-containing precursors and the crystallization of titania upon thermal treatment. Finally, we review four emerging fields including photocatalysis, photovoltaic devices, sensing and biomedical applications of mesoporous titania materials. Because of its high surface area, controlled porous structure, suitable morphology and semiconducting behavior, mesoporous titania is expected to be used in innovative applications.

The effect of a Schiff-base ligand N,N'-bis[(Z)-(2-nitrophenyl)methylidene]propane-1,3-diamine; (Salpn(NO2)2)) on the size and optical properties and the effect of time in preparation of TiO 2 nanoparticles in a two-step sol-gel method were investigated. Different amounts of Schiff-base ligand were applied and the as-prepared products were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectrum, Electron Dispersive X-ray spectroscopy (EDX) and ultraviolet-visible (UV-Vis).
