“…Besides, noble metals are also widely studied as dopants. 123,124 Charge redistribution and a synergistic effect among different elements can be achieved to enhance the charge transport and optimize the Gibbs free energy during catalytic reactions, which can further improve the catalytic activity and stability. Cao et al highlighted atomically dispersed Ir atoms doped into a Co 3 O 4 lattice for acidic OER catalytic reaction, in which the Ir sites were conducive to the formation of *OOH intermediates because of the strong hydrogen-bonding interactions, as shown in Fig.…”

Palladium metal catalysts have emerged as the preferred choice for alkaline formate oxidation reaction (FOR) due to their high activity. However, their strong binding with adsorbed H (H ad ) allows H ad to occupy the active site, resulting in slow FOR kinetics. Herein, we developed a ZrO 2 /Pd/C catalyst to decrease the H ad binding strength on Pd active sites, thereby enhancing the FOR in alkaline media. Through experimental investigations and density functional theory (DFT) calculations, we elucidated the relationship between the d-band center of Pd and hydrogen binding energy (HBE). Our findings reveal that electron transfer from ZrO 2 to Pd, driven by the work function disparity, results in a downshift of the d-band center of Pd. This shift weakens the HBE at Pd active sites, facilitating the desorption of H ad intermediates and thereby improving catalytic efficiency. As a result, the ZrO 2 /Pd/C catalyst demonstrated a 2.8-fold increase in activity over commercial Pd/C, exhibiting a lower peak potential and a significantly higher peak current of 1787 mA mg −1 . This work advances our understanding of the interplay between electronic structure and catalytic performance, setting a benchmark for high-performance electrocatalysts in energy conversion technologies.
