Abstract

Here we demonstrated that Au can be more reactive than Ni in Au/Ni heteronanostructures and be etched out first by oxidization with HAuCl4. Ligands were proven to determine the conversion pathways and structures of final products. These abnormal ligand-manipulated redox reactions may provide more possibilities for the chemical transformation of existing nanostructures into more complex ones.
