| 英文摘要 | This study focus on specifying the roles of solvent ethylene glycol (EG) and polymers for synthesis ofuniformly distributed magnesium oxide (MgO) nanoparticles with average crystallite size of around 50 nm through a modified polyol method. Based on different characterization results, it was concludedthat, Mg2+ ions was precipitated by the -OH and CO32- ions decomposed from urea in ethylene glycol (EG) medium (CO(NH2)(2) -> NH3+ HNCO, HNCO + H2O. NH3+ CO2), thus forming well crystallized Mg5 (CO3)(4)(OH)(2)(H2O)(4) precursor which could be converted to MgO by calcination. Surface protectorsPEG and PVP have no obvious influences on cyrtsal structure, morphology and size uniformity of asprepared precursors and target MgO nanoparticles. In comparison with polymers PEG and PVP, solventEG plays an important role in controlling the morphology and diameter uniformity of MgO nanoparticles.
