Revisiting the activity origin of the PtAu<sub>24</sub>(SR)<sub>18</sub> nanocluster for enhanced electrocatalytic hydrogen evolution by combining first-principles simulations with the experimental <i>in situ</i> FTIR technique

Abstract
We combined first-principles calculations and in situ FTIR characterizations to reveal that the enhanced HER activity of the PtAu 24 (SR) 18 nanocluster is contributed not only by the central Pt atom but also by the exposed bridged Au sites.
