“…TiO2 nanoparticles, aggregated from smaller anatase or rutile nanoparticles ranging in size from 20 to 50 nm, were synthesized by the precipitation of TiCl4 with ammonium hydroxide by using nonionic water/Triton X-100/hexanol/cyclohexane microemulsions with a water fraction of 8% and subsequent calcination at different temperatures [55]. 0D TiO2 nanoparticles in amorphous or crystalline form in controlled sizes were synthesized from hydrated reverse micelles [56][57][58].…”

There has been exponential growth in research activities on nanomaterials and nanotechnology for applications in emerging technologies and sustainable energy in the past decade. The properties of nanomaterials have been found to vary in terms of their shapes, sizes, and number of nanoscale dimensions, which have also further boosted the performance of nanomaterial-based electronic, catalytic, and sustainable energy conversion and storage devices. This reveals the importance and, indeed, the linchpin role of nanomaterial synthesis for current nanotechnology and high-performance functional devices. In this review, we provide an overview of the synthesis strategies for designing metal oxide nanomaterials in zerodimensional (0D), one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D) forms, particularly of the selected typical metal oxides TiO2, SnO2 and ZnO. The pros and cons of the typical synthetic methods and experimental protocols are reviewed and outlined. This comprehensive review gives a broad overview of the synthetic strategies for designing "property-on-demand" metal oxide nanostructures to further advance current nanoscience and nanotechnology.

Mono-dispersed titanium glycolate sphere powders were successfully synthesized through a homogeneous nucleation and growth process. The obtained titanium glycolate sphere powders showed a fine size distribution and shape. On calcination, the titanium glycolate spheres lost chemically bound organic compounds, and changed to anatase (500°C) and rutile (900°C) titania spheres. Titania films fabricated with the synthesized titanium glycolate spheres exhibited marked photocatalytic activity and effective reusability. The fabricated films were characterized by X-ray diffraction, scanning electron microscopy, and thermogravimetric and differential thermal analyses.

“…It has wide range of applications such as pigments, photocatalysts, solar cells, dielectric ceramics, sensor materials, etc. 5) 7) In the meantime, with the growing interest in nanoscience and nano technology, a wide variety of approaches such as solgel, 8), 9) hydrolysis, 10) reverse micelles, 11) chemical vapor deposition 12) and hydrothermal synthesis 13) have been developed to form the welldefined mesostructured titania as advanced materials with specific functions. For example, Yusuf et al 14) prepared mesoporous titania materials by the gelation of titanium alkoxide solution in the presence of polyethyleneglycol (PEG) and/or cetyltrimethylammoniumchloride (CTAC) as tem plating agent.…”
