| 中文摘要 | Hydrothermal method had been used to successfully synthesize the nanocrystalline spinel zinc manganese oxide (ZnMn2O4) directly from Zn(CH3COO)(2) . 2H(2)O, NaOH, Mn(NO3)2 and 14 0, at 170 degrees C for the reaction time of 48h. The effects of the synthesis conditions, such as the Zn/Mn molar ratio, the reaction temperature, the reaction time, the zinc source and the concentrations of NaOH and H2O2 on the formation of the Zn-Mn spinel were investigated. The products were characterized by means of X-ray diffraction (XRD), inductively coupled plasma-atomic emission spectroscopy (ICP-AES). The results indicated that the compositions of the Zn-Mn spinel with the tetragonal structure were Zn1.14Mn1.86O4, Scanning electron microscope (SEM) and transmission electron microscopy (TEM) images showed that the products at 170 degrees C were with square-shaped nanocrystalline spinel with the particle size of about 20-50 nm. The thermal behaviors of the products were investigated by thermogravimetric analysis (TG). (C) 2007 Elsevier Ltd. All rights reserved. |
