Cover Feature: Remarkable Carbon Dioxide Hydrogenation to Ethanol on a Palladium/Iron Oxide Single‐Atom Catalyst (ChemCatChem 11/2018)

The Cover Feature shows that Pd single atoms dispersed over Fe3O4 are active in the selective hydrogenation of CO2 to ethanol, but if the reaction is conducted over Pd clusters the products are CO and CH4. In their Communication, F. J. Caparrós et al. used HAADF‐STEM to show the progressive transformation of a Pd/Fe3O4 catalyst containing Pd single atoms into Pd clusters and nanoparticles upon heating, and correlate it with the catalytic transformation of CO2. By comparing with other inorganic oxide supports decorated with Pd single atoms, the results show that a specific interaction between Pd single atoms and Fe3O4 originates a particular architecture for C−C coupling. More information can be found in the Communication by F. J. Caparrós et al. on page 2365 in Issue 11, 2018 (DOI: 10.1002/cctc.201800362).
