英文摘要: Nest-like alkaline magnesium carbonate spheres were successfully prepared by precipitation of boiling Mg(NO(3))(2) solution by adding hot K(2)CO(3) solution. Thin alkaline magnesium carbonate nanoplates, which can convert to nest-like magnesium oxide (MgO) without changes of morphology by calcination, are self-assembled to nest-like spheres with a cave in the center of each particle. The obtained materials were characterized by nitrogen adsorption-desorption, X-ray diffraction, scanning electron microscopy, infrared spectroscopy, and thermogravimetry. The results showed that 150 m(2)/g of surface area and 0.51 cm(3)/g of pore volume were obtained for the nest-like MgO. Moreover, 92.36% selectivity for acetol was achieved in the conversion of 1,2-propylene glycol over the MgO with nest-like structure.
