CHAPTER 1 Liquid-phase synthesis of nanoparticles and nanostructured materials on changing their physical properties; (7) size and shape of NPs and nanostructures could be controlled quite well by the most liquid-phase synthesis methods (depending on the method used). Chemical purification and size separation techniques, such as chromatography and high-performance liquid chromatography (HPLC) are not required; (8) postsynthesis techniques are available for formation of clusters [6] and 2d superlattices [7] from the as-prepared NPs and nanostructures. The liquid-phase synthesis can be classified into: (1) top-down approaches, where bulk materials are etched in an aqueous solution for producing NPs or nanostructures, for example, the synthesis of porous silicon by electrochemical etching; and (2) bottom-up approaches, where atoms/molecules via self-assembly, in general, are gathered together to form NMs and mixed in a controlled fashion to form a colloidal solution (Fig. 1.2). NPs produced by liquid-phase synthesis methods can remain in liquid suspension for further use or may be collected by filtering or by spray drying to produce a dry powder. Liquid-phase synthesis methods from a solution of chemical compounds include, but are not limited to, chemical stain etching, colloidal methods, coprecipitation, electrochemical deposition, direct precipitation, sol-gel processing, microemulsions method, reverse micelle synthesis, hydrothermal synthesis, template methods, polyol method, and laser ablation.

“…Zn 2 TiO 4 has also been tested for efficient organic dye decomposition [4][5][6]. These nanoparticles have been investigated for dye sensitized solar cell and as a good dielectric material for microwave devices in area of mobile telephones, satellite communication and detection of ethanol vapour applications [7][8][9][10][11][12]. In the present work, we have demonstrated the growth of extremely low dimensional Zn 2 TiO 4 nanoparticles by solid state reaction method and compared with previously published results [5].…”

In this work, the ZnO-TiO2 mixed phase nanoparticles were prepared by solid state reaction method by using ZnO and TiO2 powder as precursors. The X-ray diffraction pattern shows a dominant phase of Zinc Orthotitanate (Zn2TiO4). The average particle size (58?18 nm) calculated by the analysing FESEM data closely matches with the particle size calculated by Scherrer?s equation. The calculated average particle size is significantly smaller than the previously published results of nanoparticles, prepared by same method. In the Brunauer-Emmett-Teller (BET) study the specific surface area of the nanoparticles was found as 8.78 m2/g which is similar to the surface area reported in this material prepared by mechanochemical method. The method which we report is simpler and cost effective unlike the previous reported.

Diblock copolymers have been used in sol-gel synthesis to successfully tailor the nanoscale morphology of thin ZnO films. As the fabrication of several-micron-thick mesoporous films such as those required in dye-sensitized solar cells (DSSCs) was difficult with this approach, we exploited the benefits of diblock-copolymer-directed synthesis that made it compatible with screen printing. The simple conversion of the diblock copolymer ZnO precursor sol to a screen-printing paste was not possible as it resulted in poor film properties. To overcome this problem, an alternative route is proposed in which the diblock copolymer ZnO precursor sol is first blade coated and calcined, then converted to a screen-printing paste. This allows the benefits of diblock-copolymer-directed particle formation to be compatible with printing methods. The morphologies of the ZnO nanostructures were studied by SEM and correlated with the current density-voltage characteristics.
