摘要：

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.
