Owing to defined morphology, high surface area and various application, iron oxide have received extensive attention. Their synthesis still focuses on either hard or soft template method. However, they are tedious, harmful, low stability and crystallinity. In this study, our synthesis method was newly developed to prepare metal oxalates by using both of saccharide and PVP, and then the metal oxide and carbide were prepared by thermal decomposition. This method could control its shape and change into phase such as oxide, carbide. Moreover, it was advantageous in low cost, environment friendliness, easy preparation. |
