Fig. 1. (a) Schematic diagram illustrating the consecutive broadening of the Ni d-band, which downshifts the d-band center in composition-adjustable Ni-Bx. (b) Schematic showing the tunable hydrogen-adsorption dynamics to achieve the optimal Hads/Hdes balance. Reproduced with permission from Ref. [7]. Copyright 2025, Springer Nature.

Fig. 2. (a) High-resolution B 1s XPS spectra. (b) Normalized XANES spectra. (c) FT-EXAFS spectra in R space. Wavelet transforms of Ni K-edge EXAFS data of Ni foil (d), Ni-Bx/CdS-5 (e), Ni-Bx/CdS-50 (f), and Ni-Bx/CdS-200 (g). (h) Diagram illustrating the broadening of d-band to increase the antibonding occupancy to weaken Ni-Had bonds. (i) Calculated ΔGH* values of multiple structures. Reproduced with permission from Ref.
