“…8C shows the XPS results of Ti 2p in all catalysts. For each sample, two characteristic peaks attributed to Ti 2p 3/2 at 458.6 eV and Ti 2p 1/2 at 464.4 eV showed up, indicating the presence of Ti 4+ [50]. As the XPS results shown in our previous study [6], the binding energies of Ti 2p 3/2 and Ti 2p 1/2 in FeTiO x were smaller than those in pristine TiO 2 due to the strong interaction between iron and titanium species.…”

“…The main usage of titania is used to decompose the toxin organic compound like dye from the textile industry [2]. The dye liquid pollutant flowing to the river without prior processing can influence the environmental health [3][4]. Generally, dye such as rhodamine-B, naphthol blue black, MB, and congo red [5] can be assumed as a long chain organic compound that makes it difficult to be decomposed with the conventional chemistry reaction.…”

“…Because of its highly efficient photoreactivity, biological and chemical inertness, cost effectiveness, non-toxicity, and long-term stability against photocorrosion and chemical corrosion, titanium dioxide has been frequently employed in the environmental treatment and purification purposes [18][19][20][21][22]. Anatase TiO 2 has been identified as the most effective and useful photocatalyst under near UV illumination [23].…”

Anatase nanocrystals were successfully synthesized and deposited onto polyacrylonitrile fibers with photocatalytic self-cleaning activity using the sol-gel process at low temperature. The original and treated samples have been characterized by several techniques such as scanning electron microscopy, fourier transform infrared spectroscopy, x-ray diffraction, diffuse reflectance spectroscopy, thermogravimetric analysis and differential scanning calorimetry. The TiO 2 nanoparticles, have been found to form a homogeneous thin film on the fiber surface. The photocatalytic activity, tested by measuring the degradation of adsorbed Eosin Yellowish dye. The photoactivity of the titanium dioxide coated fibres is much higher than that observed in case of untreated fibers. The photocatalytic selfcleaning properties of the treated fibers was fully maintained performing several cycles of photodegradation. This preparation technique can be also applied to new fabrics to create self-cleaning properties in them. The thermogravimetric study of PAN/TiO 2 composite showed a slight increase of weight loss in the second step, which implied that, the dehydrogenation and oxygen uptake reactions would be promoted by the TiO 2 to some extent.Keywords: Polyacrylonitrile; Titanium dioxide; Thermogravimetric analysis; Differential scanning calorimetry; Photodegradation; Eosin Yellowish e-mail: Shalkeh737@gmail.com INTRODUTIONPolyacrylonitrile (PAN) is one of the most widely used precursor polymers for making high performance carbon fibers [1][2][3][4][5]. Study of the degradation of polyacrylonitrile has been a subject of interest for decades owing to its commercial value for the production of carbon fibers [6][7][8][9][10]. Spectroscopy, including infrared, ultraviolet, solid-state nuclear magnetic resonance (NMR) and x-ray photoelectron spectroscopy (XPS), and thermal analysis, including differential scanning calorimetry (DSC), differential thermal analysis (DTA) and thermogravimetric analysis (TGA), are the common tools in the study of polyacrylonitrile degradation [11][12][13][14].Semiconductor photocatalysis has been gathering much attention recently due to its promising application in chemical conversion and storage of solar energy for solar cells, hydrogen production, refractory pollutants elimination and self-cleaning surface [15][16][17][18].Among various oxide semiconductor photocatalysts, titanium oxide (TiO 2 ) has been proven so far to be the most promising material used for both fundamental research and practical applications. Because of its highly efficient photoreactivity, biological and chemical inertness, cost effectiveness, non-toxicity, and long-term stability against photocorrosion and chemical corrosion, titanium dioxide has been frequently employed in the environmental treatment and purification purposes [18][19][20][21][22]. Anatase TiO 2 has been identified as the most effective and useful photocatalyst under near UV illumination [23].The pairs of free electrons and holes are formed in the conduction and va...
