Abstract

A novel bimetal cluster [Au₂₈Cu₁₂(SR)₂₄](PPh₄)₄ (SR = 2,4-dichlorothiophenol) has been successfully synthesized, which can be viewed as a Au₄@Au₂₄ core and four trimeric Cu₃(SR)₆ staples. Compared to monometallic Au₂₈(TBBT)₂₀ and Cu₂₈(CHT)₁₈(PPh₃)₃ clusters, the [Au₂₈Cu₁₂(C₆H₄Cl₂S)₂₄](PPh₄)₄ cluster has much higher catalytic efficiency for nitrate electroreduction to ammonia.
