【摘要】 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.更多还原

【Abstract】 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.更多还原
