(A) Illustration of the amalgamation reaction, converting monometallic seeds into intermetallic NCs. As‐synthesized PdGa, PdIn, PdZn, AuGa₂, Cu₂Ga, Ni₂Ga₃, and Ag₃Ga intermetallic NPs are shown in TEM images (B to H) and STEM EDX maps (B to E and G). Line profile scans for AuGa₂ and Ni₂Ga₃ NPs (E and G) highlight the compositional uniformity of the intermetallic NPs.
