Effect of deposition conditions on properties of nanostructured magnesium hydroxide powders

Effect of deposition conditions on properties of nanostructured magnesium hydroxide powders Change in the dispersity, microstructure, and adsorption properties of mesoporous magnesium hydroxide powders synthesized by the precipitation method from solutions upon introduction of surfactants and under the action of microwave and ultrasonic irradiation was studied.

Abstract

Change in the dispersity, microstructure, and adsorption properties of mesoporous magnesium hydroxide powders synthesized by the precipitation method from solutions upon introduction of surfactants and under the action of microwave and ultrasonic irradiation was studied. Highly dispersed nanostructured Mg(OH)2 powders were obtained with average sizes of primary and secondary particles of, respectively, 13–27 and 180–383 nm. The specific surface area, pore volume, and average pore diameter of the samples under study varied, depending on the preparation conditions, within the ranges 86–98 m2 g–1, 0.491–0.737 cm3 g–1, and 24–32 nm, respectively. It was shown that highly dispersed mesoporous magnesium hydroxide powders can be directionally synthesized by the precipitation method, which opens up wide opportunities for their application as nanoreactors for synthesis of nanosize isolated particles and development of poly-path catalysts on their basis.
