This work reports on the synthesis of different morphologies of gold nanoparticles using a microwave assisted route that is rapid, in situ and seedless. Unlike many currently employed fabricating methods, this method takes place in a single step in microwave. Gold nanospheres with an average particle size of 26 nm were synthesized with only using fructose as a novel reducing agent without any other addition of stabilizers. Branched Gold nanostars were fabricated using fructose, trisodium citrate and NaOH. Varying the concentrations of the Au and NaOH also resulted in the formation of stable gold nanospheres with particle sizes of 4.8 nm and 13 nm respectively. Using fructose along with triethanol amine led to the formation of homogeneously distributed gold nanoflowers. The mechanism for the formation of various morphologies is also presented. Such morphologies are of potential interest in applications such as sensing and catalysis due to the well understood size dependent behaviour of Gold.

这项工作报道了使用微波辅助途径快速，原位和无核地合成金纳米颗粒的不同形态。与许多当前采用的制造方法不同，该方法在微波中一步进行。仅使用果糖作为新型还原剂，不添加任何其他稳定剂，即可合成平均粒径为26 nm的金纳米球。使用果糖，柠檬酸三钠和NaOH制备了支链金纳米星。改变Au和NaOH的浓度还导致形成稳定的金纳米球，其粒径分别为4.8nm和13nm。果糖与三乙醇胺一起使用可导致形成均匀分布的金纳米花。还介绍了形成各种形态的机制。
