Titelbild: Origin of the Hydrophobic Behaviour of Hydrophilic CeO₂ (Angew. Chem. 35/2023)

The CeO2 (100) surface , despite its strongly hydrophilic nature, exhibits hydrophobic behaviour when immersed in water. This effect is induced by the first water layer that is in immediate contact with the hydroxylated CeO2 (100) surface. This ordered water layer creates a key-lock H-bond pattern with the underlying surface hydroxyl groups, hindering the interactions with liquid water. The hydrophobicity is manifested by a measurable water contact angle and a considerable diffusion enhancement of the confined liquid water as compared with bulk water, as reported by Lorenzo Agosta, Kersti Hermansson et al. in their Communication (e202303910).
