Abstract Heterodimers of metal nanocrystals (NCs) with tailored elemental distribution have emerged as promising candidates in the field electrocatalysis, owing to their unique structures featuring heterogeneous interfaces distinct components. Despite this, rational synthesis heterodimer NCs similar composition remains a formidable challenge, and impact on electrocatalysis has remained largely elusive. In this study, Pd@Bi‐PdBi are synthesized through an underpotential deposition (UPD)‐directed growth pathway. pathway, UPD Bi promotes Volmer‐Weber mode, allowing for judicious modulation core‐satellite careful control supersaturation kinetics. Significantly, employed electrocatalytic process ethylene glycol (EG) high activity selectivity. Compared pristine Pd octahedra common PdBi alloy NC, structure endows them highest performance EG best selectivity (≈93%) oxidizing glycolic acid (GA). Taken together, work not only heralds new strategy UPD‐directed bimetallic NCs, but also provides design paradigm steering electrocatalysts.
