General synthesis and atomic arrangement identification of ordered Bi-Pd intermetallics with tunable electrocatalytic CO₂ reduction selectivity.

ABSTRACT: Intermetallic compounds (IMCs) with fixed chemical composition and ordered crystallographic arrangement are highly desirable platforms for elucidating the precise correlation between structures and performances in catalysis. However, diffusing a metal atom into a lattice of another metal to form a controllably regular metal occupancy remains a huge challenge. Herein, we develop a general and tractable solvothermal method to synthesize the Bi-Pd IMCs family, including Bi₂Pd, BiPd, Bi₃Pd₅, Bi₂Pd₅, Bi₃Pd₈ and BiPd₃. By employing electrocatalytic CO₂ reduction as a model reaction, we deeply elucidated the interplay between Bi-Pd IMCs and key intermediates. Specific surface atomic arrangements end
