| 摘要: 以草酸和醋酸盐为原料，用室温固相化学反应首先合成出前驱配合物二水合草酸镍和二水合草酸锌，进而二水合草酸镍和二水合草酸锌分别在380℃和460℃热分解2 h，得到产物纳米氧化镍和氧化锌。用X-射线粉末衍射、透射电镜对产物的组成、大小、形貌进行表征。结果表明，产物纳米氧化镍为球形立方晶系结构，平均粒径均为40 nm左右，产物氧化锌为粒度分布均匀的球形六角晶系结构，平均粒径约为20 nm。 |

| Abstract: NiO and ZnO nanocrystalline materials were obtained by decomposition of precursors NiC2O4·2H2O and ZnC2O4·2H2O at 380℃、 460℃. The reaction precursors were synthesised by solid state reaction of H2C2O4·2H2O with Ni(Ac)2·4H2O and Zn(Ac)2·2H2O at room temperature. TEM studies show that the NiO and ZnO crystalline in cubic and hexagonal structure with spherical parties and uniform size distribution of 40 nm and 20 nm. |
