摘要

As the global textile dyeing industry expands, more freshwater sources are being contaminated by toxic substances, threatening ecosystems and endangering wildlife. In the present study, efforts have been made in the field of clean water and sanitation by eliminating Crystal Violet and Acridine Orange dye from wastewater using Indium doped SnSe2 catalyst via an efficient photocatalysis process. The crystals In0.15Sn0.85Se2 have been synthesized using vapor transport method. Elemental confirmation of the grown compound has been evaluated using Energy-dispersive X-ray spectroscopy (EDS). Structural information like unit cell structure, lattice parameters, unit cell volume etc. have been calculated using Powder x-ray diffraction (XRD). The morphology of In0.15Sn0.85Se2 powder has been studied using Scanning electron microscopy (SEM). Optical properties of grown compound have been studied using UV-Visible spectroscopy. The absorption spectrum is recorded in the wavelength range of 500 nm to 900 nm. The indirect band gap of the sample has been obtained from Tauc’s plot. In0.15Sn0.85Se2 crystal powder has been evaluated for its intended application as a photocatalyst for the degradation of Crystal Violet (CV) and Acridine Orange (AO) dyes from the wastewater. Degradation experiment of each contaminant has been studied in details and effect of different catalytic dose on the degradation (%) is also studied. Kinetic plots of the degradation process have been used for the evaluation of Pseudo first order rate of reaction. Recyclability and reproducibility analysis have been also carried out using synthesized catalysts for five experimental cycles. Results of present research evaluates applicability of doped metal dichalcogenides in efficient wastewater treatment.
