Methane activation and partial oxidation on free gold and palladium clusters: Mechanistic insights into cooperative and highly selective cluster catalysis

Faraday Discuss., 2012, 152, 337–351 (DOI: 10.1039/C1FD00025J). Amendment published 16th November 2012.

Due to an error in the mass calibration of the first mass-selecting quadrupole the wrong cluster size was selected for palladium. Thus, the reactivity measurements were not performed on the palladium clusters Pd_x⁺ as stated in the paper but instead on its mono-oxides Pd_xO⁺. For a detailed discussion of the cluster distribution produced by the sputter source and the corresponding mass selection please refer to Phys. Chem. Chem. Phys., 2012, 14, 9364. Throughout the whole paper all educts and products denoted as Pd_xC_yD_z⁺ must instead be labelled Pd_xOC_yD_z⁺. This error does not affect the deduced reaction mechanisms, the interpretation of the data, or the conclusion of the paper, while, however, the binding energies of CD₄ to Pd_x⁺ given in Table 1 are incorrect. In the meantime, we also investigated the reactivity of the bare Pd_x⁺ toward CD₄ and determined the correct binding energies. The corrected Table 1 should therefore now read:

Table 1. Experimental binding energies of CH₄ to Au_x⁺ (x = 2–4) and CD₄ to Pd_x⁺ (x = 2–4) as determined by employing RRKM theory under assumption of a ‘loose’ TS

E₀/eV E₀/eV

Au₂⁺ 0.91±0.04 0.83±0.10

Au₃⁺ 0.72±0.07 0.78±0.10

Au₄⁺ 0.64±0.04 0.37±0.10

	E₀/eV	E₀/eV
Au₂⁺	0.91±0.04	0.83±0.10
Au₃⁺	0.72±0.07	0.78±0.10
Au₄⁺	0.64±0.04	0.37±0.10

Details of the reactivity of the bare palladium clusters Pd_x⁺ will be given in a separate publication, explicitly comparing the ability of Pd_x⁺ and Pd_xO⁺ for methane activation and dehydrogenation.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
