Atomically Precise Au₂₄Pt(thiolate)₁₂(dithiolate)₃ Nanoclusters with Excellent Electrocatalytic Hydrogen Evolution Reactivity.

ABSTRACT: [Au₂₄Pt(C6)₁₈]⁰ (C6 = 1-hexanethiolate) is twice as active as commercial Pt nanoparticles in promoting the electrocatalytic hydrogen evolution reaction (HER), thereby attracting attention as new HER catalysts with well-controlled geometric structures. In this study, we succeeded in synthesizing two new Au-Pt alloy nanoclusters, namely, [Au₂₄Pt(TBBT)₁₂(TDT)₃]⁰ (TBBT = 4-tert-butylbenzenethiolate; TDT = thiodithiolate) and [Au₂₄Pt(TBBT)₁₂(PDT)₃]⁰ (PDT = 1,3-propanedithiolate), by exchanging all the ligands of [Au₂₄Pt(PET)₁₈]⁰ (PET = 2-phenylethanethiolate) with mono- or dithiolates. Although [Au₂₄Pt(TBBT)₁₂(TDT)
