Synthesis of metal coordinated FexSy-alginate composite at gel-liquid interface for dye degradation

Abstract

In recent years, exploring an intermediate gel phase formed between solid and liquid mediums to synthesize nanostructures has gained research momentum. With the pH of the precursor as the driving force, a variety of nanostructures can be synthesized in the gel reaction medium. Therefore, in this work, an eco-friendly and economical sodium alginate is employed to form FexSy at the gel-liquid interface. The effect of pH of the sulphur source (Na2S) is varied, and the related changes in the nature of the synthesised compound are investigated. FT IR and UV-Visible spectroscopic techniques have been done to confirm the presence of functional groups and panchromatic visible light absorption for all the FexSy -sodium alginate compounds. Further, this synthesized catalyst was used in the photocatalytic degradation of organic effluents.
