Abstract
modulates the electronic structure of both Ru and Ir sites, resulting in the lowest reaction energy barriers of Ru and Ir sites for the HER and OER, respectively, which thermodynamically explains the enhancement of the catalytic activity. Besides, the introduction of Ir atoms also enhances the demetallation energy of Ru atoms and strengthens the structural stability of the crystal, leading to the improved stability of the catalyst. This work provides an effective strategy for construction of high-performing catalysts by precisely controlling the electronic structure and active sites of polymetal atoms.
