Abstract:
The Fe 0 /C 3 N 4 /MoS 2 heterostructure was fabricated through photochemical synthesis that was free of NaBH 4 . Specifically, the g-C 3 N 4 /MoS 2 (GCNM) composite was used as the substrate. Visible light excited the electrons from the valence band of the GCNM in the substrate, and the excited electrons reduced the Fe 2+ ions in the solution nearby GCNM to Fe 0 and then created the Fe 0 /C 3 N 4 /MoS 2 heterostructure. Small Fe 0 (<9 nm) dots well dispersed on the GCNM surface were obtained, because the diffusion of the Fe ions in the solution and the diffusion of the electrons on the GCNM substrate restricted the growth of Fe 0 nanoparticles. The smaller size of Fe 0 provided a larger number of active metal centers and improved the carrier separation efficiency. As a result, the Fe 0 /C 3 N 4 /MoS 2 heterostructure exhibited superior catalytic properties in the redox reactions of rhodamine B, Cr(VI), Pb(II), and Cd(II). It could also be readily recycled without severe loss of catalytic performance. © 2017
