CuO/Sm2CuO4 heterointerfaces with Sm-derived Lewis acid sites for efficient nitrate-to-ammonia electroreduction.
The high-rate and device-level performance of Cu-based catalysts for electrocatalytic nitrate reduction to ammonia (NO3RR) remains constrained by sluggish hydrogenation of downstream nitrogen-containing intermediates, inefficient utilization of surface active hydrogen (H), and unstable Cu valence states. Herein, rare-e...
