Field Emission Properties and Fabrication of CdS Nanotube Arrays
A large area arrays (ca. 40 cm(2)) of CdS nanotube on silicon wafer are successfully fabricated by the method of layer-by-layer deposition cycle. The wall thicknesses of CdS nanotubes are tuned by controlling the times of layer-by-layer deposition cycle. The field emission (FE) properties of CdS nanotube arrays are investigated for the first time. The arrays of CdS nanotube with thin wall exhib...
متن کاملStructural manipulation of the photocatalytic activity of TiO2 nanotube arrays
Highly ordered TiO2 nanotube arrays on Ti substrates were prepared by an electrochemical anodization process in a mixture of glycerol and water containing 0.5 wt% NH4F and then thermally annealed from 400 C to 600 C. The sample structures were characterized by scanning electron microscopy and X-ray diffraction measurements, where the nanotube pore diameter and length were found to increase with...
متن کاملPhotocatalytic methane decomposition over vertically aligned transparent TiO2 nanotube arrays.
We report here on a study of vertically aligned TiO(2) nanotube arrays grown by the one-step anodic oxidation technique and their photocatalytic performance for methane decomposition. Quantitative activity data as a function of film thickness is obtained.
متن کاملFabrication of Heterogeneous TiO2-CdS Nanotubular Arrays on Transparent Conductive Substrate and Their Photoelectrochemical Properties
This paper describes an easy and time-saving strategy for the fabrication of heterogeneous nanotubular arrays of TiO2-CdS (TCHNTAs) on transparent conductive glass (FTO) and their photoelectrochemical properties. The use of transparent FTO instead of opaque Ti substrate allows incident light from the substrate side. The anodized TiO2 nanotubular arrays were firstly detached from Ti substrate by...
متن کاملPhotocatalytic reduction of methylene blue by TiO2 nanotube arrays: effects of TiO2 crystalline phase
TiO2 nanotube arrays were synthesized by anodization of Ti metal sheets followed by thermal annealing at elevated temperatures from 400 to 600 C. Scanning electron microscopic measurements showed that dense arrays of nanotubes were produced with the inner diameter about 100 nm, wall thickness 35 nm, and length about 10 lm. X-ray diffraction measurements showed that the as-prepared nanotubes wer...
