•Synthesis of AgBiS2/rGO composites via facile solvothermal route.•AgBiS2/rGO composite ensured by structural and vibrational analysis.•AgBiS2 embedded on rGO sheets exhibits large surface area.•Intercalation of AgBiS2/rGO reduce the optical bandgap.•AgBiS2/rGO composition exhibits low charge transfer resistance.
AgBiS2-rGO hybrid nano composite has been synthesized by the facile solvothermal technique. The phase formation has been identified by structural analysis which confirmed the formation of AgBiS2-rGO hybrid composite. Raman analysis ensured the presence of AgBiS2, GO and defect state of the graphene. The morphology of composite shown as flakes composed of sphere shaped structure aggregate on the rGO sheets and also well aligned crystallinity with lattice spacing of 0.28 nm of AgBiS2. The embedded AgBiS2 flakes on rGO sheets are highly favourable for fast electron transfer because of its large surface area. The absorption spectrum gradually increased in the near-IR region with the increased content of GO. Tauc plot was used to estimate the optical band gap. The impedance analysis exposed the less charge transfer resistance with the increased GO composition. These results have confirmed the formation of AgBiS2 on rGO and interaction between them. |
