Magnesium hydroxide nanoparticles synthesized in water-in-oil microemulsions

Facile preparation and application of magnesium hydroxide assembly spheres

“…In recent years, Mg(OH) 2 with different morphology has been successfully synthesized by different approaches or by use of different preparation conditions, e.g. hydrothermal [9], ultrasound-assisted [10], and direct synthesis [11,12], by in-situ preparation [13], in water-in-oil microemulsions [14], and by the spinning disk reactor method [15], etc [16][17][18]. Among the products obtained, assembly spheres with very large surface area have become the focus of much interest, because of their good suspension properties and high surface activity [19,20].…”

Self-growth of micro- and nano-structured Mg(OH)2on electrochemically anodised Mg–Li alloy surface

“…The sharp and intense peak at 3700 cm À1 can be assigned to the O-H stretching in the crystal structure of Mg(OH) 2 . [5,20] The broad band centring at 3450 cm À1 is due to the O-H stretching vibrations of adsorbed water molecules and the surface hydroxyls disturbed by the hydrogen bonds. [5,29] The broad absorption band at 1440 cm À1 can be attributed to the bent vibration of H-O-H in absorbed water.…”

“…Many methods have been developed to synthesise nano-Mg(OH) 2 with versatile morphological nanostructures, such as onedimensional nanorods and nanowires, two-dimensional plate-like and lamellar nanocrystals, and three-dimensional sphere and flower-like nanostructures. The synthesis methods include hydrothermal reaction, [4][5][6][7][8][9] solvothermal route, [10][11][12] precipitation, [13][14][15][16][17] microwave-assisted syntheses, [18] sonochemistry method, [19] water-in-oil microemulsion, [20] anodisation [21][22][23][24] or corrosion of magnesium, [25,26] electrodeposition, [27][28][29] and liquid-solid arc-discharge technique. [30] Anodisation of metal at high voltage is a conventional facile method for the preparation of well-aligned nanotube arrays of metal oxides, such as anodised aluminum oxide and TiO 2 .…”

Alkaline-Earth Metal Carbonate, Hydroxide and Oxide Nano-Crystals Synthesis Methods, Size and Morphologies Consideration

“…30 shows these unique structures. Preparation of Mg(OH) 2 nanoparticles in water-in-oil microemulsions [121] displays a platelet shape and the thickness is ca. 20 nm.…”

“…The particle size of different samples indicated that small particles were obtained in small micelles (at low ω 0 ). The particle sizes from SEM images were seemingly larger than the mean sizes of micelles as a result of the coalescence of nanoparticles in different micelles caused by the collision of micelles [121]. Rezaei et al [122] synthesized nanocrystalline magnesium oxide with high surface area.…”
