Photoelectrochemical properties and the detection mechanism of Bi2WO6 nanosheet modified TiO2 nanotube arrays.
Bi2WO6 nanosheet modified TiO2 nanotube arrays were synthesized by an anodization method combined with sequential chemical bath deposition for enhancement of the photoelectrochemical detection performance. The structures, morphologies and elemental compositions of the nanotube arrays were characterized with X-ray diffraction, scanning electron microscopy and X-ray photoelectron spectrometry. Bi...
متن کاملVisible-light-driven photoelectrochemical and photocatalytic performances of Cr-doped SrTiO3/TiO2 heterostructured nanotube arrays
Well-aligned TiO2 nanotube arrays have become of increasing significance because of their unique highly ordered array structure, high specific surface area, unidirectional charge transfer and transportation features. However, their poor visible light utilization as well as the high recombination rate of photoexcited electron-hole pairs greatly limited their practical applications. Herein, we de...
متن کاملC3N4-sensitized TiO2 nanotube arrays with enhanced visible-light photoelectrochemical performance.
A C3N4-sensitized TiO2 nanotube array-based photoanode was designed and fabricated via the in situ growth of C3N4 on the surface of TiO2 nanotubes. It shows stable and significantly improved PEC activity for hydrogen generation under visible light irradiation with a hydrogen production rate of about 19.1 μmol h(-1) (a Faradaic efficiency of nearly 100%).
متن کاملCarbon nitride polymer sensitized TiO2 nanotube arrays with enhanced visible light photoelectrochemical and photocatalytic performance.
Novel carbon nitride polymer sensitized TiO(2) nanotube arrays with high photocatalytic activity and photoelectrochemical response under visible light irradiation are prepared by electrodeposition.
متن کاملCdS or CdSe decorated TiO2 nanotube arrays from spray pyrolysis deposition: use in photoelectrochemical cells.
In the present work we report on an investigation of TiO(2) nanotube arrays sensitized by low band-gap materials, such as CdS and CdSe, prepared by the one-step spray pyrolysis deposition method, which is very suitable for mass production, and their performance in photoelectrochemical cells.
