摘要
采用液相还原法,以PVP为分散剂,甲酸铵为还原剂,在30℃AgNO3溶液高速搅拌下制备得到纳米银颗粒。采用X射线衍射(XRD)、透射电子显微镜(TEM)和紫外-可见光吸收光谱(UV-Vis)对所制备样品进行表征。当PVP与AgNO3的质量比为2.2∶1,陈化时间24 h,得到立方块和六棱柱的银混合颗粒。
PVP as dispersant, ammonium formate as reductant, AgNO3 solution as material, nano-sized silver particles was prepared by liquid reduction method under 30℃ and velocity mixing. The prepared sample was characterized by XRD, TEM and UV-Vis. Cube and six prism silver hybrid particles were got when the ratio of PVP to AgNO3 was 2.2：1 and aging time was 24h.
