氢氧化镍纳米晶的制备与表面有机化

Preparation and Surface-organization of β-Ni (OH)_2 Nanocrystals

以乙醇为反应介质,浓氨水为沉淀剂,醋酸镍为镍源,在水热条件下制备了具有片状结构的β-Ni(OH)2纳米晶;然后采用种子乳液聚合的方法实现了β-Ni(OH)2纳米晶的表面有机化。通过XRD,TEM,UV-vis,FT-IR以及分散性实验对β-Ni(OH)2的结构及表面有机化进行了表征。结果表明,采用种子乳液聚合方法成功实现了片状β-Ni(OH)2纳米晶的表面有机化。

The superthin nanoflakes of β-Ni (OH)2 were synthesized using ethanol as the reactive media under hydrothermal conditions,then the surface organization of β-Ni (OH)2 nanocrystals could be realized by seed emulsion polymerization method.By XRD,TEM,Uv-vis,FT-IR and dispersing properties in different solvents,the structure and surface properties of β-Ni (OH) 2 nanocrystals are characterized.The results indicated that the method of seed emulsion polymerization successfully realizes surface-organization of β-Ni (OH)2 nanocrystals.
