Atomically thin gold nanosheets are predicted to have interesting properties but their synthesis is challenging. Here the exfoliation of two-dimensional single-atom-thick gold, termed goldene, is achieved through wet-chemically etching Ti3C2 from Ti3AuC2. The synthesized goldene has promising properties as a heterocatalyst.
