Fig. 3

a–c Ex situ SEM images of bare Zn and d–f Zn/CPZ-H anodes. g–i Ex situ LCSM images of bare Zn and j–l Zn/CPZ-H anodes. m Chronoamperograms of bare Zn//Zn and Zn/CPZ-H//Zn/CPZ-H symmetric cells at a −150 mV overpotential. Insets: types of Zn2+ diffusion and reduction processes. n Corresponding Arrhenius curves and comparison of activation energies. o Ex situ monitoring of H2 evolution flux of a Zn/CPZ-H anode. p Calculated binding energies of Zn2+-H2O, Zn2+-PASP, and Zn2+-CS. q Molecular orbital energies of H2O, PASP, and CS molecules calculated by DFT. r DFT calculations used to study the ΔGH of bare Zn, Zn/CS, and Zn/PASP. s Schematic Zn2+ deposition processes on bare Zn and Zn/CPZ-H anodes.
