Schematic illustration of size growth reaction from [Au25(SR)18] to [Au44(SR)26]2−. a Schematic energy diagram of [Aun(SR)m]q and CO-associated [Aun(SR)m]q species. E a,Au(I)-SR and E a,Au25 denotes the formation energy of [Aun(SR)nCO]0 and [Au25(SR)18CO], respectively; the relative energies are schematically drawn according to the stability of [Aun(SR)m]q species in CO-saturated solution; the dotted curves indicate non-elementary reaction pathways. b Growth pathways from [Au25(SR)18] to [Au44(SR)26]2−
