We describe the results of an X-ray absorption spectroscopy (XAS) study of adsorbate and temperature-dependent alterations of the atomic level structure of a prototypical, noble metal hydrogenation and reforming catalyst: ~1.0 nm Pt clusters supported on gamma alumina (Pt/γ-Al₂O₃). This work demonstrates that the metal–metal (M–M) bonding in these small clusters is responsive to the presence of adsorbates, exhibiting pronounced coverage-dependent strains in the clusters’ M–M bonding, with concomitant modifications of their electronic structures. Hydrogen and CO adsorbates demonstrate coverage-dependent bonding that leads to relaxation of the M–M bond strains within the clusters. These influences are partially compensated, and variably mediated, by the temperature-dependent electronic perturbations that arise from cluster–support and adsorbate–support interactions. Taken together, the data reveal a strikingly fluxional system with implications for understanding the energetics of catalysis. Here, we estimate that a 9.1 ± 1.1 kJ/mol strain exists for these clusters under H₂ and that this strain increases to 12.8 ± 1.7 kJ/mol under CO. This change in the energy of the particle is in addition to the different heats of adsorption for each gas (64 ± 3 and 126 ± 2 kJ/mol for H₂ and CO, respectively).
