Caption

Sulfur-doped NiFe layered double hydroxides (S-NiFe-LDH) were synthesized via an in-situ hydrothermal approach. The resulting catalyst delivered outstanding urea oxidation reaction (UOR) activity, stemming from an optimized electronic structure and the evolution of active sites from Fe3+/Ni2+ to high-valence Ni3+. Sulfur incorporation markedly lowers the thermodynamic barrier, synergistically boosting reaction kinetics and enabling energy-efficient hydrogen generation.
