[Display omitted] •Synthesis of Cu2SnS3 nanoparticles by hydrothermal method.•Effect of hydrothermal temperature on structural, morphological and optical has been studied.•Influence of hydrothermal temperature and its potential to degrade the Rh-B dye in aqueous medium has been studied.•Maximum degradation of 80 % of aqueous Rh-B solution has been achieved in 80 min for H190 sample under the visible light without any scavenger. Controllably synthesis of ternary Cu2SnS3 (CTS) nanoparticles using a simple and green hydrothermal method is presented in this study. The effect of synthesis temperature on the formation of CTS nanoparticles and its utilization as a catalyst for the degradation of Rhodamine B (Rh-B) dye was studied. The CTS nanoparticles were characterized by X-ray powder diffraction, Raman spectroscopy, FTIR spectroscopy, scanning electron microscopy and UV–Visible spectroscopy. The results showed that synthesized CTS nanoparticles have agglomerated morphology, with the energy band gap of 1.74 eV. Due to the lower band gap of CTS, the light absorption into the visible region extends and an even photoinduced carrier separates well so that it presented higher photocatalytic activity. With the exposure of visible light, the maximum degradation of Rh-B has been achieved.
