Fig. 6 — a The structural model of N₂H₄ adsorption on various facets of Ni₃Co alloy, and corresponding charge density difference analysis, where the yellow or cyan regions indicate the accumulation or depletion of the charge, respectively. The L_N-H and E_b are the calculated N-H bond lengths (Å) and binding energy of the intermediates on Ni₃Co alloy. b Free energy profiles of stepwise HzOR on different facets of Ni₃Co alloy. Inset is the corresponding structural evolution of reaction intermediates adsorbed on the (100) facet of Ni₃Co. Adsorption capability of (c) water or (d) hydrazine on NiCo@C/MXene or NiCo@C. e The contact angels of water (CA_water) and bubble (CA_bubble) on NiCo@C/MXene/CF or NiCo@C/CF, and the optical images of gas bubbles released from both electrodes during HER. Scale bars: 500 μm. f Chronopotentiometric curves of NiCo@C/MXene/CF and NiCo@C/CF for hybrid seawater electrolysis. g Schematic illustration of the electrocatalytic enhancement of NiCo@C/MXene/CF at large current densities by overall enhancement in interfacial properties in terms of conductivity, robustness, water/hydrazine adsorption, and gas-releasing capability.
