Abstract An energy-efficient and environmentally friendly nitrogen fixation process is urgently needed for cleaner ammonia production. In this study, a Z-scheme single-layer g-C3N4/ZnFe2O4 photocatalyst was designed, characterized and used for the cleaner production of ammonia by N2 photofixation. From the N2 photofixation evaluation experiments, the ammonia generation concentration reached about 122.3 μmol/L in 120 min. In this ammonia production process, the design of a visible-light-driven photocatalyst was energy-saving and environmentally friendly without CO2 emission, which are potential advantages in the field of nitrogen fixation.
