| 摘要 |
The invention relates to a process for preparing simple and complex metal oxides. According to the invention, the process comprises the decomposition of metal-polysaccharide precursors at temperatures of at least 400°C, for 1...10 h, where the polysaccharide is selected from starch, methyl-cellulose, alginate, carrageenan, the precursors being obtained in an aqueous medium, by the reaction between some metal sources and polysaccharide-type carbon hydrates having the role of coordination , encapsulation, stabilization agents and templates of metal cations. |
