A new generation of solid superbase derived from potassium single atoms anchored on graphene is developed by a tandem redox strategy. The source of the basicity is the single K atoms, thus differing from conventional basicity which originates from oxygen and nitrogen atoms. The high dispersion and anchoring of superbasic sites endows the catalyst with excellent activity and stability in transesterification reactions.
