Photocatalytic oxidation of nitric oxide with immobilized titanium dioxide films synthesized by hydrothermal method

Modification of PET Fabric Using Tetrabutyl Titanate by Hydrothermal Method

“…A few encrustations of coating was formed due to the adhesion of agglomerated particles (Fig.1(c) and (d)). The particle size is slightly larger than that (less than 10 nm) obtained by reference [4] using the same precursor.…”

“…al. [4]. The width of the broader peaks at 2θ= 25.7°(101), 37.8°(004), 48.0°(200), 53.8°(105), 55.0°( 211), 62.7°(204) and 75.0°(215) suggests that the size of the particle is quite small.…”

“…The exothermic peaks at 418.5 and 463. 4 (the decomposition and carbonization of PET fiber) are increased to 436.8 and 520.0 respectively, which may be due to the crystallization of TiO2 and phase transition of anatase TiO2 to rutile [17]. The TG curves of untreated and TiO2-loaded PET fabrics are exhibited in Figure 6.…”

“…The resulting titanium dioxide particles have the desired size and shape with homogeneity in composition as well as a high degree of crystallinity [3]. Its most important feature is that it favors a decrease in agglomeration among particles, narrow particle size distribution, phase homogeneity and controlled particle morphology [4]. It has been reported that the structure and morphological characters of titanium dioxide particles are markedly influenced by the process conditions.…”

“…Technical Paper achieved [4]. Different layers of titanium dioxide were also immobilized on polypropylene fabric using titanium trichloride (TiCl3) as the precursor by hydrothermal method so as to obtain the highly active buoyant photocatalysts.…”
