通过室温固液反应及机械球磨法合成对——甲砜苯丝氨酸合铜 ( II)纳米晶 ,并通过元素分析 ,红外光谱及 X射线粉末及 TEM电子透镜对其性质进行了表征。研究表明 ,该纳米晶的平均粒径 72 nm,其组成为 ( CH3 SO2 C6H4 CHOHCHNH2 COO) 2 Cu。该纳米晶属正交晶系 ,晶胞参数 a=0 .3 894 nm,b=0 .3 91 2 nm,c=0 .3 890 nm,为一新型纳米材料 The p-sulfophenylalanine copper (II) nanocrystals were synthesized by solid-liquid reaction and mechanical milling at room temperature. Their properties were characterized by elemental analysis, IR, X-ray powder and TEM electron lens. The results show that the average diameter of the nanocrystals is 72 nm, and its composition is (CH3 SO2 C6H4 CHOHCHNH2 COO) 2 Cu. The nanocrystalline is an orthorhombic system with unit cell parameters of a = 0.3894 nm, b = 0.3112 nm, c = 0.3890 nm, a novel nanomaterial
