Аннотация

Nanocomposites highly loaded with various iron oxides were obtained by thermal treatment of SBA-15 mesoporous silica soaked in concentrated freshly prepared ferric oxalate aqueous solution. Ultradispersed iron oxide particles appeared to cover external surface of the matrix as well as to be embedded into the depth of silica. We showed that CO evolving during the thermal decomposition of ferric oxalate added at the second impregnation stage is able to reduce the iron(III) oxide preliminary formed by oxidative thermolysis of the salt having been initially loaded.
