Facet Engineering and Fe─N─Co Bridged Heterojunction Enable Fe₃O₄@C@ZIF67 as High-Performance Photocatalyst for Ammonia Synthesis.

ABSTRACT: Ammonia synthesis is vital for global fertilizer production but traditionally relies on the energy-intensive Haber-Bosch process, a major contributor to CO₂ emissions. Photocatalytic nitrogen reduction reaction (PNRR) offers a sustainable alternative by harnessing solar energy under ambient conditions. However, challenges such as low nitrogen adsorption, poor conductivity, and high electron-hole recombination of the photocatalysts limit their efficiency. This study introduces an Fe₃O₄@C@ZIF67 core-shell photocatalyst featuring an Fe─N─Co bridged Z-scheme heterojunction. This design incorporates carbon-coated Fe₃O₄ in ZIF67-D (ZIF67-dodecahedron) with exposed (211) crystalline facets to enhance nitrogen adsorption. Fe─N₄ and
