Free-standing membranes from the chemical exfoliation of mesoporous amorphous titania thin film

Thin films are typically bound to their substrate, limiting their integration on rough, porous, curved or chemically/thermally sensitive surfaces. Instead of employing tedious and expensive back-etching processes, certain chemical routes...

Zinc porphyrin/mesoporous titania thin film electrodes: a hybrid material nanoarchitecture for photocatalytic reduction

In this work, photocatalytic reduction of methyl viologen is achieved using zinc tetra(4-N-methylpyridyl)porphine (ZnP) functionalized mesoporous titania thin films (MTTF). Also, ZnP sensitizing and photophysical properties are retained in the hybrid material.

Synthesis of a mesoporous titania thin film with a pseudo-single-crystal framework by liquid-phase epitaxial growth, and enhancement of photocatalytic activity

An anatase-phase mesoporous titania thin film with a pseudo-single-crystal framework was facilely synthesized by an inexpensive chemical process.

Influence of Growth Temperature on TiO2 Nanostructures by Hydrothermal Synthesis

Titanium dioxide (TiO2) shows a great interest in solar cell application due to its morphology and crystalline structure. Moreover, it is an affordable compound that could make solar cells more economical than traditional silicon solar cells. In this study, one-step hydrothermal method is demonstrated to synthesis TiO2 nanorods/nanoflowers morphology on different hydrothermal reaction temperature. Increasing the reaction temperature could influence the formation of highly crystalline rutile phase of titania thin film. Moreover, the growth mechanism under different reaction temperatures has pronounced effects on the preferred orientation, morphologies and sizes of the structure. The results serve as guidance principle in preparing high quality solar cell specifically in heterojunction thin film fabrications.
