## Description

- description: Two dimensional (2D) crystals have attracted strong interest as a new
    class of proton conducting materials that can block atoms, molecules and ions
    while allowing proton transport through the atomically thin basal planes. Although
    2D materials exhibit this perfect selectivity, the reported proton conductivities
    have been relatively low. Here we show that vacancy-rich titania monolayers are
    highly permeable to protons while remaining impermeable to helium with proton
    conductivity exceeding 100 S cm-2 at 200 oC and surpassing targets set by industry
    roadmaps. The fast and selective proton transport is attributed to an extremely
    high density of titanium-atom vacancies (one per square nm), which effectively
    turns titania monolayers into angstrom-scale sieves. Our findings highlight the
    potential of 2D oxides as membrane materials for hydrogen-based technologies.
