Item type:Publication, Synthesis of vanadium oxide/titanium dioxide nanocomposites via sonochemical and hydrothermal process and their utilisation for energy storage application(2014-01-01); This work focuses on the synthesis of V<inf>2</inf>O<inf>5</inf>/TiO <inf>2</inf> nanocomposites by sonochemical and hydrothermal process. First, titanium dioxide (TiO<inf>2</inf>) nanopowders were synthesised by sonochemical process using titanium isopropoxide as a titanium source. Meanwhile, hydrothermal process was employed to modify the structure of commercial V <inf>2</inf>O<inf>5</inf> powder to be nanorod-like structure V <inf>2</inf>O<inf>5</inf> to increase its specific surface area. Structural and morphological properties of the composites were characterised by X-ray diffraction, scanning electron microscope and transmission electron microscope. The XRD results indicate that the crystallisation of the composite corresponds to anatase and orthorhombic structures of TiO<inf>2</inf> and V <inf>2</inf>O<inf>5</inf>, respectively. The significant variation of charge storage properties of the composites under ultraviolet irradiation was obtained by varying V<inf>2</inf>O<inf>5</inf> content in the composite. Results suggest that V<inf>2</inf>O<inf>5</inf> loaded into the nanocomposite plays a key role as a storage material of photoelectrons generated by TiO<inf>2</inf> illuminated by ultraviolet irradiation.

Item type:Publication, Effect of tin loading on physical properties and phase transformation of as-synthesized Zn-Sn-O compound powder synthesized by co-precipitation method(2014-01-01); Zinc-Tin oxide compounds (Zn-Sn-O) were successfully prepared via a facile co-precipitation process using zinc dichloride dihydrate as the zinc source and tin tetrachloride pentahydrate as an additive source. The as-prepared product of Zn-Sn-O powders with various Sn additive contents (0-60 %wt) were obtained without calcinations process. The effect of Sn additive on structural and microstructure properties of the samples were characterized by X-ray diffraction(XRD), scanning electron microscope(SEM). The results indicate that the crystallinity and morphologies of ZnO nanoparticles are significantly influenced by Sn additive. The phase formations of Zn-Sn-O including ZnO, ZnSn(OH)<inf>6</inf> were observed depending on the Sn-additive composition.1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Physical properties of V-doped TiO2 nanoparticles synthesized by sonochemical-assisted process(2013-05-01); V-doped TiO<inf>2</inf> nanoparticles were synthesized by sonochemical process using titanium isopropoxide as a titanium source, vanadyl acetylacetonate as a dopant source. Sonication was conducted using sonic horn operated at 20 kHz for 20 min until the completely precipitated product was reached. The as-synthesized precipitates with various vanadium dopant (1-5 mol %) were calcined at 500-1000 °C for 4 h. The relevant physical properties of the nanoparticles were characterized by X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM) and transmission electron microscope (TEM). The anatase phase TiO<inf>2</inf> nanoparticles can be synthesized by sonochemical process. Post calcinations process results in the anatase-to-rutile phase transformation and the enhancement in crystallinity with increasing temperature. The results also indicate good incorporation of V ions in TiO<inf>2</inf> lattices and significant effect of V dopant on alternation of interplanar spacing of TiO <inf>2</inf>. © 2012 Elsevier Ltd and Techna Group S.r.l. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Titanium dioxide/Vanadium oxide nanocomposites synthesized via sonochemical and hydrothermal process for energy storage application(2013-03-13); V<inf>2</inf>O<inf>5</inf>/TiO<inf>2</inf> nanocomposites were synthesized via sonochemical and hydrothermal process. At first, titanium dioxide (TiO <inf>2</inf>) nanopowders were synthesized by sonochemical process using titanium isopropoxide as a titanium source. Meanwhile, hydrothermal process was carried out to modify the structure of commercial V<inf>2</inf>O<inf>5</inf> powder to be nanorod-like structure V<inf>2</inf>O<inf>5</inf> with increasing specific surface area. Structural and morphological properties of the composites were characterized by XRD and SEM, respectively. The XRD results indicated that the crystalline of the composites corresponds to anatase and orthorhombic structures of TiO<inf>2</inf> and V<inf>2</inf>O<inf>5</inf>, respectively.
