【摘要】 以草酸和醋酸盐为原料，用低热固相化学反应合成出前驱配合物ＮｉＣ２Ｏ４·２Ｈ２Ｏ，ＣｕＣ２Ｏ４ 和ＺｎＣ２Ｏ４·２Ｈ２Ｏ，再分别在３５０℃，３００ ℃和４６０℃热分解２ｈ，得到纳米ＮｉＯ，ＣｕＯ和ＺｎＯ。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，纳米ＮｉＯ为球形立方晶系结构，平均粒径约为４０ｎｍ 左右；纳米ＣｕＯ为球形单斜晶系结构，平均粒径约为３０ｎｍ 左右；ＺｎＯ为粒度分布均匀的球形六角晶系结构，平均粒径约为２０ｎｍ 。更多还原

【Abstract】 NiO, CuO and ZnO nanocrystalline materials were obtained by decomposition of precursors NiC 2O 4·2H 2O, CuC 2O 4 and ZnC 2O 4·2H 2O at 350℃, 300℃ and 460℃ respectively. The reaction precursors were synthesized by solid state reaction of H 2C 2O 4·2H 2O with Ni(Ac) 2·4H 2O , Cu(Ac) 2·H 2O or Zn(Ac) 2·2H 2O at low heating temperature. XRD and TEM experimental results show that the cubic NiO, monoclinic CuO and hexagonal ZnO are in the form of spherical particles. The average particle size is distributed about 40nm,30nm and 20nm respectively.更多还原
