Interfacial Chemical-Bonded MoS 2 /In–Bi 2 MoO 6 Heterostructure for Enhanced Photocatalytic Nitrogen-to-Ammonia Conversion

Photocatalytic nitrogen reduction reaction (pNRR) is considered an ideal NH3 synthetic technology. Although catalysts prepared for pNRR under mild conditions have been extensively developed, they still face limitations of insufficient N2 adsorption/activation and low NH3 selectivity. Herein, a MoS2/In–Bi2MOO6 heterojunction catalyst with an interfacial chemical bond was constructed by the electrostatic self-assembly method. Efficient spatial separation of photogenerated electron/hole pairs and accelerated carrier transfer dynamics were facilitated due to the formation of a Mo–S bond at the interface between MoS2 and In–Bi2MoO6. The crystal orbital Hamiltonian population (COHP) analysis further confirmed that…
