Preparation of self-supporting hierarchical nanostructured anatase/rutile composite TiO2 film

Abstract

Via the combination of an electrospinning method with a hydrothermal reaction, a large-scale cedar-like hierarchical nanostructured TiO(2) film with an anatase/rutile composite phase was fabricated.

Solar Cells by Design: Photoelectrochemistry of TiO2 Nanorod Arrays Decorated with CdSe

“…Synthesis of TiO 2 NR and Nanoribbon Films: A TiO 2 NR array on conducting glass electrodes was prepared by the hydrothermal method developed by Chen and co-workers with some modifications [45]. While preparing the manuscript, we noticed that a similar synthetic route to NRs was published recently [46].…”

Template-free formation of vertically oriented TiO2 nanorods with uniform distribution for organics-sensing application

“…Among the three different crystal structures of TiO 2 , rutile, anatase, and brookite, rutile is the thermodynamically stable phase, whereas anatase has been generally accepted to have a higher photocatalytic activity than rutile owing to its anomalously large Born effective charge tensor as the result of the presence of enhanced Ti(3d states)-O(2p states) hybridization [25]. The photocatalytic activity of anatase TiO 2 can be greatly improved by mixing rutile nanostructures due to the mixed crystal effect [26,27]. Therefore, safe and simple formation of TiO 2 nanorod arrays with anatase or anatase/rutile structure is significant for their application in photovoltaic devices and photocatalysis.…”

Self catalytic growth of SnO2 branched nanowires by thermal evaporation

“…These nanostructures provide interconnections of different functional elements. Branched nanostructures of semiconducting oxides such as ZnO [5], SnO 2 [6], In 2 O 3 [7], and TiO 2 [8] have been grown by different techniques and used in different applications. Among them, SnO 2 nanostructures are particularly important because of their outstanding applications such as Li-ion batteries [2] gas sensors [3], UV detectors [9], and field emitters [10].…”
