Interfacial Chemical-Bonded MoS₂/In–Bi₂MoO₆ Heterostructure for Enhanced Photocatalytic Nitrogen-to-Ammonia Conversion

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(8), P. 6292 - 6304

Published: April 10, 2024

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 selectivity. Herein, a MoS2/In–Bi2MOO6 heterojunction catalyst with interfacial chemical bond was constructed by the electrostatic self-assembly method. Efficient spatial separation photogenerated electron/hole pairs accelerated carrier transfer dynamics were facilitated due to formation Mo–S at interface between MoS2 In–Bi2MoO6. The crystal orbital Hamiltonian population (COHP) analysis further confirmed that electrons transferred from into antibonding activate adsorbed N2, favoring nitrogen-to-ammonia (N2-to-NH3) conversion. resultant NH3/NH4+ production rate 3% MoS2/In–Bi2MoO6 reached 90 μmol·g–1·h–1, representing significant improvement over pure Bi2MoO6, while NO3– minimal. Introducing as cocatalyst effectively inhibited oxidation NO3–, achieving selective pNRR. This work provides foundation photocatalytic fixation, offering valuable insights clean NH3.
