The nanostructured oxide materials are actively studied as they possess a number of unique physical and chemical properties such as high surface area, unusual adsorption properties, rapid diffusion, high strength, wettability and mechanical stability. Among the known metal oxides, magnesium oxide is widely studied, because it is a solid with a high degree of ionicity and it has a simple stoichiometry and crystal structure. Magnesium oxide has found application as adsorbent, catalyst and in determination of the contamination of chemicals and toxic substances and their subsequent treatment. This is important for water and gas purification. In this work mesoporous magnesium hydroxide and oxide were synthesized from water solutions by easy and cheap wet chemistry method. The crystal structure, particle size distribution and adsorption properties of 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 up opportunities to use them as nanoreactors for the synthesis of isolated nano-sized particles and poly directions catalysts.
