Abstract
Two-dimensional materials like graphitic carbon nitride are gaining more interest because of their desirable features such as high thermal stability, high chemical resistance, affordability, non-toxic and non-corrosive properties. However, the recombination of photogenerated charges limits the photocatalytic efficacy g-C3N4. To address this issue, a quick and affordable hydrothermal technique was employed to create a ternary nanocomposite of molybdenum disulfide (MoS2), reduced graphene oxide (rGO), and g-C3N4 that efficiently limited charge recombination and increased photocatalytic efficiency. The synthesized g-C3N4/rGO/MoS2 nanocomposite showed enhanced photocatalytic activity due to the multi-step charge transfer mechanism and greater utilization of visible light. When compared with both pure g-C3N4 and g-C3N4/MoS2 nanocomposites, the ternary nanocomposite significantly degrades 94.1 % Rhodamine-B dye. In order to assess the properties of the nanocomposite, SEM, XPS, X-ray diffractometer, photoluminescence, and electrochemical impedance spectra were all used. This work illustrates the capability to improve dye degradation performance utilizing a simple and cost-effective method.
