Bi2MoO6 was synthesized on fibrous CuO/CF via a hydrothermal method, and its performance was subsequently evaluated. To ensure stable adhesion, copper foam (CF) was employed as the conductive substrate. The synthesized Bi2MoO6@CuO/CF composite demonstrates significantly enhanced light absorption capabilities. Electrochemical tests indicate that the composite exhibits a synergistic effect between enhanced visible light absorption and improved electrochemical reaction by specific charge transfer pathways, leading to increased activity in the nitrogen reduction reaction (NRR). The experimental data reveal that the nitrogen fixing efficiency and Faradaic efficiency of the Bi2MoO6@CuO/CF composite are 48.61 μg·cm−2·h−1 and 10.5 %, respectively. Compared to CuO/CF, the nitrogen fixation performance of the composite is 1.78 times higher, and its Faradaic efficiency is improved by 2.05 times. Ultimately, this novel composite photocatalyst, with its robust nitrogen fixation and light absorption capacities, represents a promising alternative to the current energy-intensive nitrogen fixation processes.
