[求助] 金簇浓度的计算

请问合成的金簇的浓度应该怎么计算啊?最终形成的金簇的物质的量是不是与开始时加入的HAuCl4的物质的量一样啊?

在还原剂足够的情况下,可以假设所有的金都被还原成了金纳米簇,这样金纳米簇的金原子的摩尔浓度和起始的氯金酸的摩尔浓度相同。如果进而假设该金簇主要是有22个金原子组成的金簇,则金簇的摩尔浓度则只需将金的摩 ...

我想问一下:银纳米簇的浓度也是这么计算吗?(最近在学习银纳米簇的合成)

If there is enough reductant during the synthesis, one can assume all Au is reduced and form AuNCs. In case you know the atomic composition of these AuNCs, e.g., Au8 or Au 25, then you can estimate the molar concentration of these particles. Or else, you can only use the weight concentration, such as XX µg/ml, to denote the concentration of AuNCs.
