Diatomite combined with certain metal‐organic frameworks (MOFs) is shown to be an effective CO 2 absorbent, although diatomite alone is regarded as inert with respect to CO 2 absorption. This finding opens the prospect of reactivating millions of tons of diatomite for CO 2 absorption. It also shows for the first time that diatom frustules can act as CO 2 buffers, an important link in a successive biological CO 2 concentration mechanism chain that impacts on global warming.
