A facile synthesis of mesoporous composite materials by a particle coagulation-precipitation method |
| 초록 |
Mesoporous composite materials of one dimensional particles and two-dimensional nano-sheets have been prepared successfully by a simple coagulation-precipitation method. Ferromagnetic magnetite, spinel-type crystalline copper chromite, and amorphous copper manganate was used as one dimensional particles. While the synthetic hectorite particle was used as two-dimensional nano-sheet. In a typical process metal oxide particles were thoroughly dispersed in aqueous solution and then the pre-swelled silicate dispersion was added to the particle suspension under vigorous stirring, followed by adjusting the pH of mixed suspension to 2~3 using acetic acid, resulted in a highly viscous gel-like product. The gel-like product was precipitated by centrifuging, washed with the mixed solvent of distilled water and acetone, then dried at 120℃ for 2h. Thus prepared composite powders exhibited dramatically enhanced specific surface area and pore volume. |
