| 摘要: 以反式二氯二胺合铂（trans-PtCl2（NH3）2）为Pt源，溴化亚铜（CuBr）为Cu源，在油胺（OAm）体系中采用一锅法快速制备得到笼状PtCu3空心结构，同时用XRD，TEM，HRTEM和高角环形暗场扫描透射电子显微技术[HAADF-STEM，high angle annular dark field （HAADF） scanning transmission electron microscopy （STEM）]。对产物的结构及形貌进行动态的，多角度的表征，所得PtCu3空心结构对温度敏感，过高的温度会加快原子的扩散速率，导致空心结构坍塌。 |

| Abstract: Cage-like PtCu3 hollow nanostructure was rapidly prepared by simple one-pot synthesis method using trans-PtCl2(NH3)2 as Pt source and CuBr as Cu source in oleylamine (OAm). The structure and morphology of the obtained nanocrystal were characterized by XRD, TEM, HRTEM and High Angle Annular Dark Field-Scanning Transmission Electron Microscopy (HAADF-STEM). The PtCu3 hollow structure is sensitive to temperature. The diffusion rate of atoms will be accelerated if the temperature is too high, which will result in the collapse of the hollow structure. |
