Triethanolamine assisted sol-gel approach for obtaining two-dimensional magnesium aluminate nanosheetsTriethanolamin unterstutzte Sol-Gel-Methode zur Herstellung von zweidimensionalen Magnesium-Aluminat-Nanofolien

Aqueous-phase synthetic route was applied for the preparation of magnesium aluminate spinel nanosheets with two-dimensional nanostructure through a sol-gel combustion approach, where triethanolamine was employed as a complexing agent and fuel. Results demonstrate that the as-synthesized two-dimensional nanosheets are well crystallized and show high purity. The pure magnesium aluminate nanoparticles with an average crystallite size of 25 nanometers were obtained at 1200 degrees C. Also, the two-dimensional magnesium aluminate powder contain nanosheets with thicknesses in the 20 nanometers-30 nanometers range, and the lateral size is in the range of similar to 10 micrometers-30 micrometers.
