The non-delayable quest of sustainable energy infrastructure based on converting solar energy onto energy carrying molecules has renewed interest in tailored catalysts for water splitting and CO2 reduction reactions (CO2RR).

Abstract

The non-delayable quest of sustainable energy infrastructure based on converting solar energy onto energy carrying molecules has renewed interest in tailored catalysts for water splitting and CO2 reduction reactions (CO2RR). In this context iridium, has emerged as one of the most interesting materials. In the attempt to identify a direct correlation between particular atom arrangements with a precise electrochemical activity, the survey of several few-atom iridium clusters was started. Herein, we report preliminary results on a small Ir9 cluster deposited by a new size-selective method developed at the Argonne National Laboratory. The cluster-coated electrode was cycled in 0.1 M NH4Cl and KOH under N2 and CO2. Finally, the CV and SWV curves were compared in order to gain insights on its potential behavior as catalyst for the CO2RR.
