Abstract

Observation of Brønsted acid sites: By enhancing the solid-state NMR signals of <sup>17</sup> O at natural abundance with dynamic nuclear polarization (DNP), Pruski et al. were able to measure oxygen-proton distances accurately with sub-picometer precision. The results give insight into the Brønsted acidity of a range of solid acid catalysts.

Item Type: Article
