Structural and optical behavior of SnS2/NiFe2O4 NCs prepared via novel two-step synthesis approach for MB and RhB dye degradation under sun light irradiation

The present investigation focuses on facile two-step synthesis approach fabrication of tin sulfde (SnS2)/ nickel ferrite (NiFe2O4) nanocomposites (NCs) for the frst time. The crystallinity and phase purity of the prepared material was investigated in powder X-ray difraction (PXRD) studies. The presence of functional groups (stretching and bending vibration) was primarily determined by the Fourier Trans-
form Infrared Spectroscopy (FT-IR) analysis. As well as, optical behavior of the synthesized samples was determined in UV–Vis absorption spectroscopic studies, and the presence of surface defects was established by PL spectroscopic tudies. From the FESEM analysis, sponge-like structure was attained and Ni, Fe, Sn, S and O elemental component was determined by the EDAX spectrum analysis. The as-
prepared SnS2/NiFe2O4 NCs exhibit superior photocatalytic performance and high stability toward the reduction of methylene blue (MB) and rhodamine B (RhB) dyes under irradiation of direct sunlight. The synthesized anocomposites showed an ef- cient photocatalytic activity with a high reaction kinetic rate.
