Abstract: Nest-like alkaline magnesium carbonate spheres were successfully prepared from self- assembled thin nanoplates, which can convert to nest-like magnesium oxide (MgO) without changes of morphology by calcination. The obtained nest-like MgO spheres show a high specific surface area and large pore volume. A high selectivity (92.36%) for acetol can be achieved in the conversion of 1,2-propylene glycol over the MgO with nest-like structure.
