| description | α -Fe _2 O _3 /MoS _2 /rGO nanocomposites was prepared by a two-step hydrothermal method and characterized by XRD, FESEM, EDS, FTIR, and UV–vis absorption spectroscopy. The results confirmed the formation of α -Fe _2 O _3 /MoS _2 -rGO (10 wt%) nanocomposites were composed of hematite nanoparticles with particle size of 30 nm and MoS _2 /rGO composite nanosheets with maximum sheet thickness of ∼ 10 nm. Upon addition of MoS _2 -rGO (8.0 wt%) nanosheets, the band gap of α -Fe _2 O _3 nanoparticles decreased from 2.3 to 1.7 eV that was accompanied by light absorption enhancement. Owing to synergetic effect between rGO and MoS _2 nanosheets leading to suppression of charge carrier recombination, prolongation of charge carrier lifetime, improvement of the interfacial charge transfer and increase in the number of active sites in α -Fe _2 O _3 nanoparticles, as-synthesized α -Fe _2 O _3 /MoS _2 -rGO (10 wt%) nanocomposites nanocomposite showed highly enhanced photocatalytic performance for Rh B degradation under light irradiation so that complete degradation of Rh B organic dye was achieved within 30 min. |
