Engineering the growth of TiO2 nanotube arrays on flexible carbon fibre sheets

Abstract

We demonstrate the engineered growth of TiO(2) nanotube arrays on flexible carbon fibre sheets. The modification not only enables the textile to absorb ultraviolet light efficiently but also imparts large surface area and mesoporosity to the textile. This flexible nanoarchitecture greatly facilitates the purification of organic wastewater.

Enhanced photocatalytic activity of wool-ball-like TiO2 microspheres on carbon fabric and FTO substrates

“…However, the recyclability of these TiO 2 microspheres is not very good [5,[22][23][24]. Growing these TiO 2 nanomaterials on certain substrates, such as FTO and CF [27], is an ideal way to address this problem.…”

“…[11] However, recycling these one-dimensional TiO 2 nanomaterials from aqueous solution after photocatalytic reactions are not easy and these photocatalysts cause secondary pollution. [5,[22][23][24] To address this problem, growing these one-dimensional TiO 2 nanomaterials on certain substrates is an ideal way. [25] In this work, we demonstrated a facile synthesis of wool-ball-like TiO 2 microspheres composed of one-dimensional TiO 2 nanowires on fluorine doped SnO 2 (FTO) and carbon fabric using P25 as precursor by a modified hydrothermal method.…”

Effect of calcination on structural, morphological and photoelectrochemical performance of SnO2/TiO2 nanostructure films

“…There are different ways to overcome this drawback and enhance the photovoltaic activity of TiO 2 nanostructures. Among the reported various TiO 2 nanostructures such as hollow nano-spheres [1], nano-tubes [2], nano-belts [3], nano-ribbons [4], nano-rods [5], nano-wires [6], nano-fibers [7], nano-shuttles [8], nano-flowers [9] and nano-sheets [10], one dimensional (1-D) TiO 2 nanostructures, such as nano-rods and nano-wires, exhibit excellent photovoltaic properties due to the higher photon-to-electron conversion and efficient charge carrier separation and migration [11] in third generation solar cells including dye sensitized solar cells (DSSCs) [12], hybrid solar cells [13], quantum dot solar cells [14] and extremely thin absorber (ETA) solar cells [15]. Moreover, due to their wavelength, visible light scattering and absorption are improved greatly in this geometry [16].…”

Direct Growth of Bismuth Oxyhalides Nanosheet Arrays on Carbon Cloth for Recycled Photocatalytic Degradation of Dye and 4-Nitrophenol

“…19 Second, the unique 3D BiOCl/ carbon cloth can capture light from all directions, thus showing potential for application. 20 Third, suggested by previous work, the electron transfer between BiOCl and carbon will greatly retard the recombination of photoinduced charge carriers and prolong electron lifetime, which may be an important cause of the better photoactivity of BiOCl/ carbon cloth heterostructures.…”
