“…The method is based on oxidizing of Ni 2+ to NiO2 (nickel peroxide) and then converting this peroxide to NiO by treating it with ethanol in the presence of a surfactant. The use of surfactant is in fact somehow similar to the reverse -micellar method which has been recently demonstrated as a versatile route to produce a variety of nanoparticles [27,28,29,30] . The effect of different surfactants on the size of the as-prepared nanosized NiO is also investigated.…”

NiO nanoparticles have been prepared by a simple and efficient chemical precipitation method with the aid of a surfactant. In this method, NiO2 (nickel peroxide) was first prepared by oxidation of nickel (II) nitrate with hypochlorite solution. The as-prepared NiO2 was then easily converted to nanosized NiO merely by treating it with ethanol at room temperature. The fabricated NiO nanoparticles were characterized by XRD, TEM, and EDX techniques. The effect of three different surfactants viz., SLES, CTAB and Triton X-100 on the formation of NiO nanoparticles was also studied.

“…Generally the crystals adopt raphides or styloids shapes. Some studies have focused on developing and understanding interactions between calcium oxalate crystals, organic templates and additives [6,7]. For example, Langmuir monolayer [8][9][10], membrane vesicles [11], and phospholipids micelles [12] have been used for the direct crystallization of calcium oxalate.…”

Biomimetic living bi-templates, mung bean sprouts (MBS), were employed to control the crystallization of calcium oxalate dehydrate (COD). Two kinds of crystals in different shapes were simultaneously grown on the outer surface and the inner stem wall of MBS respectively. The whole process is in the living system that material flow and energy exchange ceaselessly. The products were respectively characterized by SEM, XRD. A presumable mechanism is proposed.

“…TiO2 nanoparticles with diameters varing from 10 to 20 nm were produced by the controlled hydrolysis of titanium tetraisopropoxide (TTIP) in the presence of reverse micelles formed in CO2 with the surfactants ammonium carboxylate perfluoropolyether (PFPECOO −+ NH4) (Mw = 587) and poly(dimethyl amino ethyl methacrylate-block-1H, 1H, 2H, 2H-perfluorooctyl methacrylate) (PDMAEMA-b-PFOMA) [57]. Hernandez et al [58] reported the synthesis of TiO2 nanoparticles with a mean diameter of 3.5 ± 0.7 nm inside sodium bis (2-ethylhexyl) [59]. 0D ZnO nanoparticles have been synthesized in reverse micelles or microemulsions, for instance, polystyrene-b-polyacrylic acid (PS(10912)-b-PAA(3638)) copolymer, PEG NP-5/cyclohexane, AOT, non-ionic Pluronic F127, anionic surfactant sodium dodecyl sulfate (SDS), etc.…”

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.
