Nanopowders of TiO2 obtained by combustion reaction: effect of fuels

Almeida E.P., Coutinho J.P., Freitas N.L., Kiminami R.H.G.A., Costa A.C.F.M., Lira H.L., Universidade Federal de Campina Grande, BR

The synthesis by combustion reaction to obtain TiO2 has been studied by several researchers and using different fuels. Thus, this study aimed to evaluate the effect of fuel (citric acid monohydrate, aniline, oxalic dihidrazida and [...]

Violet-Blue Emission From TiO2/SWCNT Hybrid Structure Synthesized by a Simple Chemical Route

Paul R., Kumbhakar P., Mitra A.K., NIT Durgapur India, IN

Using a lucid wet chemical process under room temperature, titania nanocrystallites of average size 5 nm have been adhered to the surfaces of SWCNT bundles. The hybrid structure has been characterized by high resolution transmission [...]

Incorporation of plasma modified multi-walled carbon nanotubes into TiO2 photoanode for dye-sensitized solar cells (DSSC)

Chan Y.F., National Cheng Kung University, TW

Dye-sensitized solar cells (DSSC) are fabricated using photoanode comprises of nanocomposite material of TiO2 and multi-walled carbon nanotubes (MWNT) treated in situ by plasma and subsequent functionalization by grafting of maleic anhydride (MA). The carboxyl [...]

Organic Solvent Dispersed TiO2 Nanocrystal Sol: Synthesis and Characterization

Rao Y.Q., Antalek B., Minter J., Mourey T., Blanton T., Slater G., Slater L., Slater G., Slater L., Fornalik J., Eastman Kodak Company, US

Anatase TiO2 nanocrystals with a mean diameter of about 10 nm were successfully synthesized through a non-aqueous sol gel route without the use of air free equipments. The nanocrystals were well dispersed in organic solvents [...]

Synthesis and Characterization of Anodized Titanium Oxide Nanotubes Arrays

Hu M.Z., Lai P., Bhuiyan M.S., Tsouris C., Gu B., Paranthaman M.P., Gabitto J., Prairie View A&M University, US

Anodized titanium oxide containing highly ordered, vertically oriented TiO2 nanotube arrays is a nanomaterial architecture that shows promise for diverse applications. In this paper, an anodization synthesis using HF-free aqueous solutions is described. The anodized [...]

A Markedly Cntrollable Adhesion of Superhydrophobic Sponge-like Nanostructure TiO2 Films

Lai Y., Lin C., Huang J., Zhuang H., Sunb L., Nguyen T., Xiamen University, CN

A method consisting of electrochemical anodization and self-assembling of hydrophobic-hydrophilic mixture has been employed to fabricate superhydrophobic sponge-like nanostructured TiO2 surfaces with remarkably controllable adhesion. Water adhesion ranged from ultra-low (5.0 N) to very high [...]

Lithium selective adsorption on low-dimensional TiO2 nanoribbons

Zhang Q-H, Li S-P, Sun S-Y, Yin X-S, Yu J-G, East China University of Science and Technology, CN

Low-dimensional TiO2-related nanomaterial with high morphology specificity, including nano-tube, -wire, -sheet, -fiber and -ribbon, had attracted particular interest in advanced applications as catalyst, solar-energy conversion semiconductor, gas sensor and electrochemical material, as it was discovered [...]

Synthesis and Testing of Metal and Nitrogen Doped Nano-TiO2

Zhang Z., Darr J.A., University College London, UK

we have adopted a novel approach to the use of continuous hydrothermal flow system (CHFS) for the synthesis of various crystalline doped anatase TiO2 nano-ceramics with high surface area (ca. 280 m2g-1) system. Their photocatalytic [...]
