Physico-Chemical Attributes and Photodegradation Assessment of Crystal Violet Dye by Utilizing TiO2/Sn2S3 (Sn=0.25, 0.50, 0.75 M) Nanocomposite Prepared Via Hydrothermal Strategy

This work aims to prepare TiO2/Sn2S3 quantum dots by simple hydrothermal method. The Sn compound present in the quantum dots were varied in the molar ratio of 0.25 M, 0.50 M and 0.75 M. Furthermore, a comparative analysis was performed using their pristine counterparts. Analysis such as XRD, UV-Visible analysis, FTIR, photoluminescence, HR-SEM, EDAX, HR-TEM, SAED and photocatalytic analysis were performed to identify the various morphology and characteristics of the samples. TiO2/Sn2S3 quantum dots possessed tetragonal (anatase) and orthorhombic crystal structure. Crystal violet dye was used to determine the degradation capability of the samples. TiO2/Sn2S3 quantum dots with a molar ratio of 0.25 Sn showed a good photocatalytic degradation efficiency of 75.93% for 60 min.
