通过刻蚀2-（二苯基膦）吡啶保护的多分散Au纳米团簇（质量为1 ~ 3 kDa），实现了纯Au25(2- nap)18和Au36(2- nap)24纳米团簇的可控合成。在80℃的蚀刻温度下合成了Au25(2-Nap)18，在50℃的蚀刻温度下合成了Au36(2-Nap)24。这表明，通过简单的调整蚀刻温度，可以实现不同原子精度的金纳米团簇的可控合成。
The controlled synthesis of pure Au25(2-Nap)18 and Au36(2-Nap)24 nanoclusters were achieved via etching 2-(diphenylphosphino)-pyridine protected polydispersed Au nanoclusters with a mass of 1 to 3 kDa. Au25(2-Nap)18 was obtained at the etching temperature of 80 °C, while Au36(2-Nap)24 was synthesized at the etching temperature of 50 °C. This demonstrates that the simple adjustment of the etching temperatures can realize the controlled synthesis of different atomically precise Au nanoclusters.
