All that glitters… The gas‐phase reactions of the bimetallic cluster ions Pt m Au n + ( m + n ≤4) with dioxygen and methane are investigated. The platinum‐rich cluster ions undergo degradation processes and dehydrogenation reactions, which are also known for pure Pt m + clusters. In contrast, the gold‐rich cluster ions are found to be unreactive, similar to the corresponding Au m + clusters. This distinct trend in reactivity (see graphic) is correlated with the systems' electronic properties changing as a function of cluster composition.
