INOR 641 |
| Highly porous materials such as mesoporous materials have generated considerable interests as a consequence of their high specific surface areas, unusual stability, well developed pores with narrow size distributions and very wide application. Here, we report the syntheses of highly ordered mesoporous transition metal oxide through a nano-casting method, utilizing ordered mesoporous silica as the rigid template. We have successfully synthesized various kinds of mesoporous transition metal oxides such as Fe2O3, Mn2O3, Co3O4, SnO2, WO3 and In2O3, which are particularly of interest in the fields of catalysis, gas sensing, rechargeable batteries and optical electronic devices. The pore structures as well as atomic structures of the mesoporous transition metal oxides can be easily controlled by varying the synthetic conditions such as preparation temperature, the amount of precursors, etc. |
