Sumario:The reactivity of iron nanocluster arrays on h‐BN/Rh(111) was studied using in situ high‐resolution X‐ray photoelectron spectroscopy. The morphology and reactivity of the iron nanoclusters (Fe‐NCs) were investigated by CO adsorption. On‐top and hollow/edge sites were determined to be the available adsorption sites on the as‐prepared Fe‐NCs and CO dissociation was observed at 300 K. C‐ and O‐precovered Fe‐NCs showed no catalytic activity towards CO dissociation because the hollow/edge sites were blocked by the C and O atoms. Therefore, these adsorption sites were identified to be the most active sites of the Fe‐NCs.
