20.500.12556/DiRROS-29095 Mnemonic rutile–rutile interfaces triggering spontaneous dissociation of water Mnemonic rutile-rutile interfaces triggering spontaneous dissociation of water Water interaction with mineral surfaces is a complex living system decisive for any photocatalytic process. Resolving atomistic structure of mineral–water interfaces is thus crucial for understanding these processes. Fibrous rutile TiO2, grown hydrothermally on twinned rutile seeds under acidic conditions, was studied in terms of interface translation, atomic structure and surface chemistry in the presence of water, by means of advanced microscopy and spectroscopy methods combined with structure modeling and density functional theory calculations. We show that fibers while staying in stable separation during their growth, adopt special crystallographic registry that is controlled by repulsion forces between fully hydroxylated and protonated (110) surfaces. During relaxation, a turbulent proton transfer and cracking of O–H bonds is observed, generating a strong acidic character via proton jump from bridge –OHb to terminal –OHt groups, and spontaneous dissociation of interfacial water via a transient protonation of the –OHt groups. It is shown, that this specific interface structure can be implemented to induce acidic response in initially neutral medium, when re–immersed. To our knowledge this is the first demonstration of a 2D, quantum confined mineral–water interface, capable of memorizing its past and conveying its structurally encoded properties into a new environment. mineral-water interfaces atomistic structure photocatalysis fibrasti rutil atomistična struktura meja mineral-voda mreža vodikovih vezi transfer protona spontana disociacija vode cepljenje vode fotokataliza strukturno modeliranje analitske metode true false true Wiley Nemčija Angleški jezik Slovenski jezik © 2023 The Authors.
