Abstract

Ammonia Electrosynthesis In article number 2504457, Myong Yong Choi and co-workers report a pulsed laser irradiation in liquids method to synthesize high-entropy rock-salt oxides (HE-RSO), achieving structural stabilization and exceptional eNO3RR activity for NH3 production. In situ Raman and DFT studies revealed that Co and Cu dual sites promote eNO3RR via the N-end pathway. Integrated into a Zn–nitrate battery, HE-RSO enabled efficient energy conversion and selective NH3 production.
