Research Article reveals how water influences alkanol dehydration in different TiO2 facets, suggesting new catalytic pathways.
In Research Article e2431054, Feng Gao, Jianzhi Hu, Yong Wang, and co-workers reveal that the stronger water inhibition of alkanol dehydration on TiO2(001) than on TiO2(101) originates from facet-dependent water–alkanol complexes. The cover depicts water molecules reorganizing adsorbed alcohol species on TiO2 through hydrogen bonding, destabilizing transition states, and elevating activation energies. This work establishes water-mediated intermediates as determinants of facet-dependent catalytic inhibition.
