Results confirmed the formation of α‒Fe2O3/MoS2 nanocomposites containing hematite nanoparticles with average diameter of 40 nm and MoS2 nanosheets with hexagonal crystal structure and sheet thickness of < 10 nm. Optical band gap measurements revealed decrease of the band gap of α‒Fe2O3 nanoparticles from 2.65 to 2.15 eV upon loading MoS2 nanosheets. The as‒synthesized α‒Fe2O3/MoS2 nanocomposites showed a high absorption capability in the visible irradiation. Photocatalytic examinations showed over 98 % degradation of Rhudamine Blue (Rh B) organic dye within 75 min. α‒Fe2O3/MoS2 nanocomposites enhanced the rate of degradation as compared to pure α‒Fe2O3 nanoparticles and MoS2 nanosheets.  UR - https://www.acerp.ir/article_90763.html L1 - https://www.acerp.ir/article_90763_1a97cb9b3e3fabee46e3cf41174df798.pdf ER -
