Abstract

Graphical abstract: An all-solid-state Z-scheme SL g-C3 N4 /ZnFe2 O4 photocatalytic system for N2 photofixation performance enhancement. Highlights: An energy-efficient and environmentally friendly N2 fixation process was realized by SL g-C3 N4 /ZnFe2 O4 photocatalyst. Ammonia generation concentration of about 122.3 μmol/L within 120 min under visible light. N2 photofixation enhancement was attributed to Z-scheme charge transfer route. 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-C3 N4 /ZnFe2 O4 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.
