“…Powder X-ray diffraction (PXRD) studies were carried out on a Bruker D8 Advance diffractometer with Ni-filtered Cu Ka radiation and a scan speed of 1°/s and scan step of 0.05°. The details of the data collection methodology and evaluation of crystallite size and cell parameters are given elsewhere [38]. The cell parameters were determined from a least-squares fitting procedure of all observed reflections with quartz as the external standard.…”

“…The TEM specimens were prepared by dispersing the powder in acetone by ultrasonic treatment, dropping onto a porous carbon film supported on a copper grid, and then dried in air. Mössbauer measurements for SnO 2 were carried out at room temperature with a conventional system operating in constant acceleration mode 49 . Dielectric measurements were carried on disks of CeO 2 nanoparticles sintered at 800 °C and 1000 °C and ZrO 2 nanoparticles sintered at 1000 °C The measurements were carried out using Hewlett Packard 4284L multifrequency LCR meter in the range of 50 Hz to 500 kHz.…”

Monophasic nanosized oxides were synthesised mainly from metal oxalate nanorods obtained using the reverse micellar method. This paper focuses on the methodology to obtain important metal oxides like tin dioxide, cerium oxide (CeO 2 ), zirconia, and zinc oxide. The effect of oxidation state of the metal ion on the morphology of the oxalates was studied. Nanorods of zinc (II) oxalate (120 nm in dia and 600 nm in length) were obtained while spherical particles of size 4 6 nm were obtained for cerium (III) oxalate. The decomposition of these precursors at higher temperature led to the formation of their respective oxides. Mixture of nanorods and nanoparticles of CeO 2 was obtained while 34 nm sized ZrO 2 nanoparticles were obtained by thermal decomposition of zirconium oxalate precursor. The dielectric constant and loss were highly stable with frequency (at room temperature) for both ceria and zirconia nanoparticles. ZnO nanoparticles (55 nm sized) were obtained by the decomposition of zinc oxalate nanorods. Three peaks corresponding to free excitonic emission, free-to-bound, and donor-acceptor transitions were observed in the photoluminescence studies at 20 K for ZnO nanoparticles.

“…These two microemulsions were then mixed to form a precipitate by either the addition of 0.1 mol L −1 NaOH solution or by stirring overnight. The white precipitate was then calcined at 60 and 500°C for 5 h to obtain crystallized SnO2 nanoparticles of 70 and 150 nm in size, respectively [62]. PdO-SnO2 nanocomposite was also prepared by precipitating Pd(OH)2 and Sn(OH)4 inside reverse micelles obtained by mixing cyclohexane (C6H12), a non-ionic surfactant (polyoxyethylene (6) nonylphenyl ether (NP-6)), and an aqueous solution containing [Sn(OH)4] 2− (0.1 mol L −1 ).…”

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.
