A continuous and compact CdS quantum dot-sensitive layer was synthesized on TiO2 nanorods by successive ionic layer adsorption and reaction (SILAR) and subsequent thermal annealing. The thickness of the CdS quantum dot layer was tuned by SILAR cycles, which was found to be closely related to light absorption and carrier transformation. The CdS quantum dot-sensitized TiO2 nanorod array photoelec...

Titanium oxide films with trilayer structure grown on fluorine doped tin oxide substrate were prepared from one-step hydrothermal process. The trilayer structure consists of microflowers, nanorod array and compact nanoparticulates, which is expected to posses the merits of good light harvesting, a high electron transport rate, while avoiding the issues of electron shunting. The photovoltaic per...

Titania (TiO2) and sodium titanate nanostructures with controllable phases and morphologies were synthesized by a hydrothermal method with titanium disulfide (TiS2) as the starting material. Sodium titanate nanobelts could be synthesized under a relatively low alkaline concentration (1 mol L(-1) NaOH) and short duration (6 h). At 3 mol L(-1) HCl, rutile TiO2 nanorods were synthesized. Anatase T...

Recyclability is an important aspect for heterogeneous photo-catalysts. Ease of recovery and stability of the photo-catalyst in terms of efficiency over the number of cycles are highly desired and in fact it is ideal if the efficiency is constant and it should not decrease marginally with each cycle. Presented here is a seminal observation in which the photocatalytic activity is shown to improv...

Because the oxides of nitrogen (NOx) cause detrimental effects on not only environment but humans, developing a high-performance NO2 gas sensor is crucial issue for real-time monitoring. To this end, metal oxide semiconductors have been employed materials. in general, semiconductor-type sensors require high working temperature, photoactivation has emerged as an alternative method realizing at r...

Electrochemical N2 reduction provides a green and sustainable alternative to the Haber-Bosch technology for NH3 synthesis. However, extreme inertness of molecules is formidable challenge, which requires development an active electrocatalyst drive reaction (NRR) production at ambient conditions. Herein, we demonstrate La-doped TiO2 nanorods as efficient NRR The optimized La-TiO2 catalyst offers ...

Carbon plasma nanocoatings with controlled fraction of sp(3)-C bonding were deposited on TiO2 nanorod arrays (TNAs) by DC magnetic-filtered cathodic vacuum arc deposition (FCVAD). The cytocompatibility of TNA/carbon nanocomposites was systematically investigated. Human umbilical vein endothelial cells (HUVECs) were cultured on the nanocomposites for 4, 24, and 72 h in vitro. It was found that p...
