Title: 100-Fold Enhancement of Charge Transport in Uniaxially Oriented Mesoporous Anatase TiO₂ Films

Abstract

Mesoporous semiconductor films are of considerable interest for applications in photoelectrochemical devices, however, despite intensive research till now, their charge transport properties remain significantly lower than their single-crystal counterparts. Herein, we report a novel low-temperature template-free technique for growing high surface area mesoporous anatase TiO2 films with a preferred [001] crystalline-orientation on FTO-coated glass substrate. Compared to mesoporous films that comprised of randomly oriented crystallites, the uniaxial orientation enables a 100-fold increase in the rate of electron transport. The uniaxially oriented mesoporous anatase TiO2 films exhibit should greatly facilitate the development and application of photoelectrochemical and electrochemical devices.

Zirconia-stabilized 25-{angstrom} TiO{sub 2} anatase crystallites in a mesoporous structure

Journal Article Elder, S H ; Gao, Y ; Li, X ; ... - Chemistry of Materials

The authors have prepared and characterized a mesoporous material where the framework, of both the as-synthesized and calcined materials, is composed of ZrO{sub 2}-doped 25-{angstrom} TiO{sub 2} anatase crystallites. The nanocrystalline framework is structured about a surfactant-templated, disordered porous network with a uniform pore diameter of 28 {angstrom}. Air calcination at 450 C removes the surfactant to yield a mesoporous solid with surface area of 330 m{sup 2}/g. The mesoporous framework and TiO{sub 2} crystallite size are surprisingly robust, and the authors observed no substantial structural differences between precalcined and calcined products.

Zirconia-Stabilized 25-AngstromTiO2 Anatase Crystallites in a Mesoporous Structure

Journal Article Elder, Scott H ; Gao, Yufei ; Li, Xiaohong S ; ... - Chemistry of Materials, 10(10):3140-3145

Presents the preparation and characterization of a mesoporous material where the framework of both the as-synthesized and calcined materials, is composed of ZrO2-doped 25-angstrom TiO2 anatase crystallites. The nanocrystalline framework is structured about a surfactant-templated, disordere porous network with a unifrom pore diamter of 28 angstrom. Air calcination at 450 degrees C removes the surfactant to eyild a mosoporous oslid with surface area of 330 m2/g. The mesoporous framework and TiO2 crystallite size are surprisingly robust, and we observed no substantial structural differences between precalcined and calcined products.
Mesoporous anatase TiO{sub 2}/reduced graphene oxide nanocomposites: A simple template-free synthesis and their high photocatalytic performance

Journal Article Zhou, Qi ; Zhong, Yong-Hui ; Laboratory of Nanomaterials and Environmental Detection, Hefei Institute of Physical Sciences, Chinese Academy of Sciences, Hefei 230031 ; ... - Materials Research Bulletin

Graphical abstract: - Highlights: • Mesoporous TiO{sub 2} nanoparticles with anatase phase were assembled on reduced graphene oxide via a template-free one-step hydrothermal method. • The TiO{sub 2}/rGO nanocomposites have better adsorption capacity and photocatalytic degradation efficiency for dyes removal. • Improved dye adsorption and photogenerated charge separation are responsible for enhanced activity. - Abstract: Mesoporous anatase phase TiO{sub 2} was assembled on reduced graphene oxide (rGO) using a template-free one-step hydrothermal process. The nanocomposites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and Brunauer–Emmett–Teller (BET) surface area.more »« less

Epitaxial Formation Mechanism of Multilayer TiO ₂ Films with Ordered Accessible Vertical Nanopores by Evaporation-Driven Assembly

Journal Article Khan, M. Arif ; Islam, Syed Z. ; Nagpure, Suraj ; ... - Journal of Physical Chemistry. C

Surfactant-templated mesoporous titania (TiO2) films have excellent physical and electronic properties, but some potential applications require films thicker than the 100-200 nm typically prepared by sol-gel coating. Here, the mechanism of forming micron-thick TiO2 films with vertically oriented nanopore channels by a layer-by-layer deposition technique (up to eight 125 nm-thick layers) is investigated. In situ grazing incidence small angle x-ray scattering (GISAXS) performed on successive layers of Pluronic F127-templated films reveals if and how epitaxially oriented layers form during aging at 4 °C. At 78% relative humidity (RH), films cast onto substrates modified with crosslinked F127 maintain (011)-oriented Im3m cubicmore »« less

Layer-by-Layer Synthesis of Thick Mesoporous TiO ₂ Films with Vertically Oriented Accessible Nanopores and Their Application for Lithium-Ion Battery Negative Electrodes

Journal Article Nagpure, Suraj ; Zhang, Qinglin ; Khan, M. Arif ; ... - Advanced Functional Materials

Abstract TiO ₂ films of varying thicknesses (up to ≈1.0 µm) with vertically oriented, accessible 7–9 nm nanopores are synthesized using an evaporation‐induced self‐assembly layer‐by‐layer technique. The hypothesis behind the approach is that epitaxial alignment of hydrophobic blocks of surfactant templates induces a consistent, accessible mesophase orientation across a multilayer film, ultimately leading to continuous, vertically aligned pore channels. Characterization using grazing incidence X‐ray scattering, scanning electron microscopy, and impedance spectroscopy indicates that the pores are oriented vertically even in relatively thick films (up to 1 µm). These films contain a combination of amorphous and nanocrystalline anatase titania of valuemore »« less
