Assembling-controlled synthesis is carried out for fabrication 0 & 2D NiCu amorphous nanoalloys through the cooperation of hard–soft interfacial templates in different template-assist routes at room temperature. The controlled fabrication of 0D nanospheres and 2D ultrathin nanofilms of NiCu amorphous alloys is attributed to the synergistic effect between structure-inducing of hard collodion membrane and the reactor volume adjusting of reverse microemulsion as well as coordination of ethylenediamine ligand. The hard artificial active collodion membrane lost the structure-inducing activity after ligand ethylenediamine coordinated with metal ions. The phase transformation behavior recordings indicate that the replacement of Ni by Cu can delay phase transformation. And as the Cu concentration increases, the kinetic ordering temperature increases. The magnetic property shows that the saturation magnetizations (Ms) and coercivities (Hc) of annealed nanoalloys decrease with the increasing of Cu concentration in NiCu system.
0 & 2D Shape-controlled NiCu nanoalloys were synthesized by the cooperation of hard–soft interfacial templates. They are amorphous nanoalloys and have the component-depend kinetic ordering temperature and magnetic property.Figure optionsDownload high-quality image (143 K)Download as PowerPoint slide
