Electronic Structure Modulation Induced by Asymmetric Cu─Ni Centers in a π‐Conjugated Triazine MOF

Advanced Materials Interfaces, EarlyView.
A π‐conjugated H3TATB‐based asymmetric bimetallic CuNi‐MOF was developed as an efficient electrocatalyst for alkaline hydrogen evolution. Benefiting from synergistic Cu–Ni interactions, enhanced charge transfer, and stabilized active sites, CuNi‐MOF delivers superior HER performance with low overpotential, improved kinetics, and 24 h durability.
