一步室温固相化学反应法合成CuO纳米粉体

Synthesis of Nanopowder CuO by One Step Solid State Reaction at Room Temperature

研究了以CuSO4·5H2 O ,CuCl2 ·2H2 O ,Cu(NO3) 2 ·3H2 O ,Cu(gly) 2 ·H2 O与NaOH为反应物 ,用一步室温固相化学反应合成CuO纳米粉体的 4个反应体系 ,用透射电镜 (TEM)和X射线衍射 (XRD)对产物进行表征 .表明产物CuO(Ⅱ )化合物与NaOH经室温固相化学反应得到单斜晶纳米CuO .另还从研磨方式。

Nanopowder CuO was synthesized by one step solid state reaction of NaOH with CuSO 4·5H 2O, CuCl 2·2H 2O, Cu(NO 3) 2·3H 2O and Cu(gly) 2·H 2O at room temperature. The products were characterized by XRD and TEM. It is shown that all products prepared from solid state reaction of Cu(Ⅱ) salts with NaOH are in monociline structure with nanosize. The effect of grinding style, ratio of reactants and reaction system on the particle size and dispersion were studied.
