文摘
Spinel-type MgAl2O4 nanoparticles with high surface area were synthesized by thermal decomposition of three different ion-pair complexes precursors, including [Mg(H2O)6][Al(dipic)2]2⋅6H2O, [Al(sal)2(H2O)2]2 [Mg(dipic)2] and [Mg(H2O)6][Al(ox)2(H2O)2]2⋅5H2O. Influence of the inorganic precursor was investigated on synthesis and textural properties of magnesium aluminate nanopowders. The precursors [Mg(H2O)6] [Al(dipic)2]2⋅6H2O and [Al(sal)2(H2O)2]2[Mg(dipic)2] displayed pure spinel-type MgAl2O4, while the sample synthesized by [Mg(H2O)6][Al(ox)2(H2O)2]2⋅5H2O precursor consisted of MgAl2O4 and MgO. The MgAl2O4 synthesized via [Al(sal)2(H2O)2]2[Mg(dipic)2] precursor exhibited higher BET specific surface area (226.7 m2 g−1) and smaller particle size than those of the samples obtained from the two other precursors.
