Abstract
Bismuth was introduced as an intermediate to produce Au-X (X = Pt and Pd) bimetallic nanoalloys using the galvanic replacement reaction. The results showed that the Au-X nanoalloys have good activity for electrocatalytic reactions in alkaline media. This strategy can provide an option for the formation of multimetal nanoalloys with similar electrochemical potentials and compositions.
