Abstract

The addition of 17OH2 to silica at room temperature leads to spontaneous hydroxyl oxygen exchange and the selective isotopic enrichment of silanols, as observed using in and ex situ17O NMR. The discovery that silanols are labile alters our understanding of the chemistry of silica surfaces.
