Prevenient dye-degradation mechanisms using UV/TiO2/carbon nanotubes process

Efficient removal of dyes in water using chitosan microsphere supported cobalt (II) tetrasulfophthalocyanine with H2O2

“…Acid Red 73 dissociate and are converted to anionic ions (1). In the presence of H + , the amino groups of chitosan became protonated (2). Then the adsorption proceeds due to the electrostatic attraction between these two counterions (3).…”

“…It is known that wastewaters containing dyes are very difficult to treat, since the dyes are recalcitrant molecules, resistant to aerobic digestion, and stable to oxidizing agents. In recent years, catalytic oxidation has been recognized as an effective method of removal of dyes in water [2,3]. Especially, the interest in catalytic oxidation based on the Fenton-like reaction is continuously growing because of the possibility of utilization of an environmentally friendly oxidant like hydrogen peroxide and readily available complexes as catalysts [4,5].…”

Fabrication of nano-TiO2/carbon nanotubes and nano-TiO2/nanocarbon black on alkali hydrolyzed polyester producing photoactive conductive fabric

“…The photocatalytic activity of nano-TiO 2 was increased in the presence of CNTs (Lee, 2004;Oh, Jung, & Ko, 2009). It has been verified organic dye decomposition by CNTs/nano-TiO 2 composites due to the photocatalytic degradation of nano-TiO 2 and electron transfer between CNTs and nano-TiO 2 (Chen, Zhang, & Oh, 2009;Jitianu et al, 2004;Kuo, 2009;Liu, Li, Zhang, Li, & Guo, 2008). The conductive textile can provide new design opportunities for electronic textile and high-performance sport wear, embedded health monitoring devices which are simple, sensitive, selective, and versatile (Liu et al, 2007).…”

Decorating and Filling of Multi-Walled Carbon Nanotubes with TiO<sub>2</sub> Nanoparticles via Wet Chemical Method

“…These composite materials have been fabricated by a range of different methods, including mechanical mixing of TiO 2 and CNTs [17], sol-gel synthesis of TiO 2 in the presence of CNTs [18], electro-spinning methods [19], electrophoretic deposition [20], and chemical vapor deposition [8]. The uniformity of the decoration of CNTs with oxide and the physical properties of the composite materials depend on the procedure of modification.…”
