以聚酰胺-胺树形分子为模板剂Cu原子簇的制备与表征

Preparation and Synthesis of Copper Cluster with Poly(amido-amine) Dendrimer as a Template

以4代端胺基的聚酰胺-胺（PAMAM）树形分子为模板剂,羟胺为还原剂,在空气中得到了分散性好、尺寸分布均匀（粒径为4-5 nm左右）、结构和性能稳定的Cu原子簇.同时,探讨了溶液的pH值对粒子的半径及分散状况的影响.

Copper cluster with main grain size of 4-5 nm, good stability and dispersion, was obtained at the presence of G （4） -NH2-PAMAM dendrimer as a template and NH2OH as a reductant in air atmosphere, The influence of the pH value on the particle size, dispersion and stability was discussed.
