SYNTHESIS AND ADSORPTION PROPERTIES OF NANOSTRUCTURED POWDERS Mg(OH)2 AND MgO
Abstract
Magnesium oxide has found applications as adsorbent, catalyst and ideutifier of the contamination of chemicals and toxic substances in the processes of water and gases purification. In this work, mesoporous magnesium hydroxide and oxide were synthesized from water solutions by easy and cheap wet chemistry method. Crystal structure, particle size distribution and adsorption properties of the synthesized powders were studied. Obtained powders of Mg(OH)2 and MgO showed sufficiently high total pore volume – 0.737 and 1.038 cm3 /g, respectively, which opens an opportunity to use them as nanoreactors for the synthesis of isolated nanosized particles and multidirection catalysts.
