Preparation Of Magnesium Titanate Nanosheets By A Modified Sol-Gel Method

Magnesium titanate (MgTiO3) nanosheets were successfully prepared by a modified sol-gel method, employing inorganic titanium trichloride (TiCl3) as Ti source, magnesium nitrate (Mg(NO3)(2) center dot 6H(2)O) as Mg source, and maleic acid as a chelating agent. The MgTiO3 sample obtained at 700 degrees C consists of nanosheets with a slight agglomeration, and the average size is about 80 nm. The average size of MgTiO3 particles becomes larger when the calcination temperature increases from 700 to 900 degrees C. It is found that high purity MgTiO3 can be successfully prepared at 900 degrees C for 2 h. The present work develops a facile and cost-effective route to prepare MgTiO3 nanosheets with good crystallinity, which is a key engineering step towards the potential size-dependent applications.
