Chem. Sci., 2025, Accepted Manuscript DOI: 10.1039/D5SC04536C, Edge Article Yuanting Lei, Lili Zhang, Xiaochen Wang, Dan Wang, Yafei Zhao, Bing Zhang, Ning Zhang, Huishan Shang Electrocatalytic nitrate-to-ammonia (NO3RR) conversion offers a sustainable alternative to the energy-intensive Haber-Bosch process. High-entropy materials (HEMs), which exploit compositional diversity, lattice distortion, and d-band modulation, demonstrate remarkable electrocatalytic potential. However,...
