摘要：
The application relates to cerium oxide-aluminosilicate tube nanocomposites. These nanocomposites can be used, for example, as components in pharmaceutical or cosmetic compositions. The nanocomposites of cerium oxide and aluminosilicate tubes contain 0.5-30% by weight of cerium oxide. The size of the cerium oxide nanoparticles is 4-15 nm. The cerium oxide-aluminosilicate tube nanocomposites are prepared by a method including the following steps: (i) preparation of an aqueous suspension of aluminosilicate tubes； (ii) deposition of cerium oxide by adding of solutions of cerium nitrate and ammonium hydroxide to stirred aqueous suspension of aluminosilicate tubes； (iii) filtering of formed sediment with subsequent washing of the sediment. The addition of cerium nitrate and ammonium hydroxide solutions is carried out gradually.
