Figure 6. (A) Calculated pDOS of Pd and Pd-B alloy models; (B) A volcano plot showing the ΔG_H* values of Pd-B alloy models containing different subsurface B concentrations as a function of their surface d-band centers. The inset shows the structural model of Pd-B systems with different subsurface B concentrations; (C) Schematic illustration of ordered interstitial B atom in Pd₂B electrocatalysts and the optimal near-surface electronic structure for HER^[118]; (D) Schematic illustration of the synthesis of ordered mesoporous PtZnM trimetals^[128]; (E) Scanning electron microscopy (SEM) image of ordered mesoporous PtZnCo trimetals.
