In this paper, rutile TiO2 nanorod arrays are fabricated by a template-free method and proposed as a promising anode for aqueous Li-ion battery. The as-prepared TiO2 nanorod arrays exhibited reversible Li-ion insertion/extraction ability in aqueous LiOH electrolyte. Moreover, galvanostatic charge/discharge test results demonstrated that the reversible capacity of TiO2 nanorods could reach about...

Plasmonic metal/semiconductor heterostructures show promise for visible-light-driven photocatalysis. Gold nanorods (AuNRs) semi-coated with TiO2 are expected to be ideally structured systems for hydrogen evolution. Synthesizing such structures by wet-chemistry methods, however, has proved challenging. Here we report the bottom-up synthesis of AuNR/TiO2 nanodumbbells (NDs) with spatially separat...

Vertically aligned TiO2 nanotubes have been fabricated on the indium-doped tin oxide (ITO) by a simple and versatile technique using the lectrochemically deposited ZnO nanorods, oriented along the c-axis, as a template in the spin-on based sol–gel reaction of a Ti precursor. The iameter, length, and shape of TiO2 nanotubes were controlled by changing the initial ZnO nanorod template and the spi...

Understanding the evolution of amorphous and crystalline phases during atomic layer deposition (ALD) is essential for creating high quality dielectrics, multifunctional films/coatings, and predictable surface functionalization. Through comprehensive atomistic electron microscopy study of ALD TiO2 nanostructures at designed growth cycles, we revealed the transformation process and sequence of at...

This paper reviews the recent development of surface-reaction-limited pulsed chemical vapor deposition (SPCVD) technique for the growth of TiO2 one-dimensional nanostructures. SPCVD uses separated TiCl4 and H2O precursor pulses, and the anisotropic growth of TiO2 crystals is attributed to the combined effects of surface recombination and HCl restructuring at high temperature during elongated pu...

In this work, nanostructured TiO2 and Cr-doped TiO2 thin films were deposited on glass substrate through sonochemical-chemical vapor deposition (CVD) method. The resulting thin films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible absorption spectroscopy, and photoluminescence spectroscopy techniques. The TiO2 thin film has nanocubic morphology and ...

We report here for the first time the synthesis of two novel hierarchical homogeneous nanoarchitectures of TiO2 nanorods branched TiO2 nanotube arrays (BTs) and P25-coated TiO2 nanotube arrays (PCTs) using two-step method including electrochemical anodization and hydrothermal modification process. Then the photocurrent densities versus applied potentials of BTs, PCTs, and pure TiO2 nanotube arr...

In this paper, N-doped TiO2 (N-TiO2) nanorod arrays were synthesized with hydrothermal method, and perovskite solar cells were fabricated using them as electron transfer layer. The solar cell performance was optimized by changing the N doping contents. The power conversion efficiency of solar cells based on N-TiO2 with the N doping content of 1% (N/Ti, atomic ratio) has been achieved 11.1%, whi...

ZnO, aside from TiO2, has been considered as a promising material for purification and disinfection of water and air, and remediation of hazardous waste, owing to its high activity, environment-friendly feature and lower cost. However, their poor visible light utilization greatly limited their practical applications. Herein, we demonstrate the fabrication of different aspect ratios of the ZnO n...

Inthiswork, Titanium dioxide (TiO2) nanostructures have beensynthesized via amicrowave assisted solvothermalmethod using titanium tetraisopropoxide (TTIP),polyvinylpyrrolidone(PVP) and Ascorbic Acid (AA) in ethanol. The mole ratio ofPVP/AA was found to be critical in determining the morphology and crystal phaseof the final product. PVP/AA mole ratio varied from 1 up to 1...
