a Energy diagram of Volmer−Tafel pathway for HER on the Rh/GDY. b TS transition state (TSs) with the NEB barriers for H2O dissociation and H migration, respectively. The pink, blue, red, and light gray spheres represent C, Rh, O, and H atoms, respectively. c Schematic illustration of the HER reaction mechanisms along the Volmer−Tafel pathway on Rh/GDY.
