Perspective: can interfacial defects enhance graphene’s reactivity for gas–surface reactions under ultra-high vacuum?

Abstract
A very recent experimental study [Proc. Natl. Acad. Sci. U.S.A. 123 (10) e2524790123] demonstrated that non-functionalized graphene (Gr) supported on silicon(111) catalyzed the decomposition of small sulfur-containing compounds under ultra-high vacuum. Accompanying density functional theory (DFT) calculations identify grain boundary defects (GBDs) and interfacial defects as the active sites. Functional carbon catalysts still encounter skepticism within the catalysis and surface science communities.
