Innenrücktitelbild: Neighbouring Synergy in High‐Density Single Ir Atoms on CoGaOOH for Efficient Alkaline Electrocatalytic Oxygen Evolution (Angew. Chem. 32/2024)

The neighbouring synergy in high‐density Ir single atoms for alkaline electrocatalytic oxygen evolution is described by Chuanyi Jia, Zhirong Zhang, and Jun Bao et al. in their Research Article (e202404418). The neighbouring Ir single atoms stabilize the *OOH intermediates via additional hydrogen‐bonding interactions, thus significantly reducing the reaction energy barriers compared to isolated Ir single atoms. The discovery of the synergetic interaction in neighbouring Ir single atoms offers guidance for developing efficient electrocatalysts.
