Tuning surface electronic properties of Ni doped Cu2O catalyst toward highly selective nitrate-to-ammonia electroreduction
The nitrate-to-ammonia electrochemical reduction reaction (NO3RR) driven by renewable energy provides a sustainable route for simultaneous wastewater treatment and green ammonia synthesis. Nevertheless, the NO3RR involves a complex multi-step proton-coupled electron transfer process, and the imbalance between proton su...
