Advanced electrocatalysts capable of bifunctional catalysis for formic acid oxidation (FAOR) and hydrogen evolution reaction (HER) have garnered significant attention due to their exceptional energy efficiency. In this research, we meticulously designed a PdCu bimetallene characterized by numerous crystalline/amorphous (c/a) interfaces robust d–sp orbital hybridization, achieved integrating the p-block metalloid boron within matrix (B-PdCu-c/a). The B-PdCu-c/a revealed multitude surface atoms unsaturated defect sites, offering abundant catalytic active sites an optimized electronic structure. B2-PdCu-c/a exhibited best performance in FAOR HER, achieving mass activity 1106 mA mgcat–1 overpotential 52 mV, respectively. Significantly, two-electrode configuration B2-PdCu-c/a∥B2-PdCu-c/a attained low cell voltage 0.19 V at 10 cm–2 during acid-assisted overall water splitting. Density functional theory (DFT) calculations indicated that c/a interface engineering hybridization synergistically pristine bimetallene. This led elevation d-band center accumulation charge interface, which enhanced adsorption intermediates, facilitated C–H bond cleavage, balanced adsorption–desorption hydrogen, thereby improving electrocatalytic activities study not only presents viable strategy effectively tuning but also offers valuable insights into development electrocatalysts.

Abstract PdCoNi trimetallic catalysts attracted extensive interest in direct formic acid fuel cells due to high poisoning resistance and activity for electro‐oxidation (FAO). Herein, a series of Pd 0.75 Co x Ni y /C alloys with modulated ratio are synthesized investigate the effect content on electronic structure FAO. The physical analysis demonstrated that introduction induces lattice strain compared monometallic catalysts. As consequence fixing total amount Ni, is restricted, perturbation successfully regulated by varying alloys. loses more electrons, bond strength Pd−H weakened, FAO enhanced first then decreased as increases. Among catalysts, 0.125 catalyst exhibits highest current density 3.253 mA cm −2 owing optimum strength. This work provides valuable guideline future studies Pd‐based
