在柠檬酸三钠存在下，通过硼氢化钠还原硝酸银制备了粒径可控的银纳米晶，然后以纳米晶为晶种合成了银纳米棒。老化对小纳米晶影响明显，但对大纳米晶影响不大，这意味着两种纳米晶的晶体表面存在不同的结构缺陷。使用一次性添加NaBH4并在0°C制备的银纳米晶体有助于生产最多且具有最大长径比的银纳米棒。只有较小且稍微老化的纳米晶体可以用作形成具有高纵横比的银纳米棒的晶种。银种子相关参数的影响可以应用于通过种子介导的生长方法合成其他各向异性纳米材料。
Silver nanocrystals with controlled particle size were prepared by reduction of silver nitrate with sodium borohydride in the presence of trisodium citrate and then silver nanorods were synthesized by using the nanocrystals as seeds. The aging has obvious influence on the small nanocrystals but little influence on the large nanocrystals, implying different structural defects on the crystal surfaces of the two kinds of nanocrystals. The use of silver nanocrystals prepared by addition of NaBH4all at once and prepared at 0°C helps produce the most silver nanorods with maximum aspect ratio. Only the smaller and slightly aged nanocrystals can be used as seeds for the formation of silver nanorods with high aspect ratio. The effects of concerned parameters of silver seeds can be applied to the synthesis of other anisotropic nanomaterials by a seed-mediated growth approach.
