Photocatalysis technology could utilize solar energy to degrade many toxic pollutants and provides possibility to deal with unsymmetrical dimethylhydrazine (UDMH) wastewater with less energy consumption. In this study, well-aligned TiO2 nanorod arrays (TiO2 NRAs) were grown directly on transparent conductive glass (FTO) via a hydrothermal method, and TiO2 NRAs/CdS heterostructure films were pre...

The paper deals with application of three nanomaterial systems: undoped TiO2, chromium-doped TiO2:Cr and TiO2-SnO2 synthesized by flame spray synthesis (FSS) technique for hydrogen sensing. The emphasis is put on the role of anatase and rutile polymorphic forms of TiO2 in enhancing sensitivity towards reducing gases. Anatase-to-rutile transformation is achieved by annealing of undoped TiO2 in a...

Titanium dioxide (TiO2) micro and nano architectures have been intensively studied in 15 the past years because of many varied applications in environmental, energy conversion, and 16 storage fields, such as heterogeneous catalysis, dye-sensitized solar cells, lithium/sodium ion 17 batteries, lithium-sulfur (Li-S) batteries, and bio-nanotechnology, etc. Especially the surface and 18 interface s...

J Abstract We report here a successful fabrication of a 3-D photoelectrode configuration having hydrothermally formed TiO2 nanotubes on parallel Ti fins. The Ti fin arrays were assembled by simple and facile spot welding of alternately tall and short Ti foil assembly, which provides signific...

Microfibrous palygorskite and tubular halloysite clay mineral combined with nanocrystalline TiO2 are incorporating in the preparation of nanocomposite films on glass substrates via sol-gel route at 450C. The synthesis is employing nonionic surfactant molecule as pore directing agent along with acetic acid-based sol-gel route without addition of water molecules. Drying and thermal treatment of c...

For the sustainable production of hydrogen by photocatalysis, the use of renewable resources such as water, organic compounds from plant biomass and earth abundant metal promoters is desired. We herein describe the previously not reported "one-pot" photoassisted synthesis of a binary metal-nitrogen promoted Cu(0)-N-TiO2 photocatalyst from a N-TiO2 precursor by photodeposition of copper directly...

Semiconductor TiO2 photocatalysis has attracted much attention due to its potential application in solving the problems of environmental pollution. In this paper, thiourea (CH4N2S) modified anatase TiO2 nanorods were fabricated by calcination of the mixture of TiO2 nanorods and thiourea at 600 °C for 2 h. It was found that only N element was doped into the lattice of TiO2 nanorods. With increas...
