Structural evolution-induced strong-coupling in CuRu-Cu2O nanocomposite enables low-overpotential electrocatalytic ammonia synthesis
Ammonia (NH3) synthesis via nitrate reduction offers a sustainable energy conversion and mitigates aquatic NO3− pollution, yet most catalysts require high overpotentials for appreciable NH3 yields. Here, we report a sulfur-leaching strategy to transform Cu1.8S/Ru heterostructures into a small CuRu-Cu2O nanocomposite wi...
