Flexible composite via rapid titania coating by microwave-assisted hydrothermal synthesis

Abstract

The aim of this work was to prepare a flexible nanocomposite from ultra-fine titanium oxide (TiO 2) growth on carbon fibre via microwave-assisted hydrothermal synthesis (MHS) and to evaluate its photocatalytic properties. The TiO 2 nanoparticles were directly grown on the carbon fibre (CF). Thus, a study comparing the conventional titania coating vs. the MHS were performed. The significant layer interaction as a function of the coating method on the visible and dark dye photodegradation performance was observed. Techniques such as X-ray diffraction, electron microscopy (field-emission scanning electron microscope (FESEM)), Raman spectroscopy, among others were used aiming to characterize the different route samples. This study reports a reproducible and single method to manufacture of nanocomposites through the growth of TiO 2 nanoparticle on CF by MHS that allow controlling the thickness layer. Similar procedure of synthesized nanocomposite could be applied in different chemical compositions to advanced applications, based on the electrochemical nanostructure.

Facile Synthesis of Silver-salicylic acid (modified)/TiO2-nanotube/Ti plates for UV-light Promoted Dye Degradation

“…Semiconductor photocatalysis has recently attracted great attentions for environmental remediation and purification through advanced oxidation processes [1,2]. Heterogeneous semiconductor photocatalysis was reported as a suitable approach to detoxification from both industrial and biological pollutants in many researches [3,4]. Among the semiconductors investigated, anatase TiO2 is one of the most commonly used materials for photocatalytic degradation of chemical and microbiological pollutants due to its non-toxic nature, low cost, abundance, UV-driven high activity, photo and thermal stability [5,6].…”
