Here, we report the development of a synthesis method to achieve IMC NCs, based on controlled amalgamation of low–melting point metals into monometallic seeds ().We recognize a seeded growth approach as a promising route for incorporating metals with differing reduction potentials in NCs during colloidal synthesis (24–28).Amalgamation refers to the process of alloying a metal with another ...
