Regulating Interfacial Water Structure on CoNi/MoN Heterostructures Boosts Electrocatalytic Nitrate Reduction to Ammonia

Carbon Energy, EarlyView.
The CoNi/MoN interface effect induces electron transfer from CoNi species to MoN nanosheets, in which electron‐enriched CoNi/MoN interface captures K+ to form K+‐H2O, facilitating H2O dissociation to provide *H for accelerating hydrogenation steps, while electron‐deficient CoNi nanoparticles enhances the NO3− adsorption and reduces the free energy ...
