Title : Sodium alginate-CuS nanostructures synthesized at the gel-liquid interface: an efficient photocatalyst for redox reaction and water remediation


Gels are an excellent reaction medium for the synthesis of nanomaterials because they represent the transition phase that exists between solids and liquids. In this study, CuS nanostructures are grown at the gel-liquid interface using an environmentally sustainable sodium alginate gel as a reaction media. The morphology of the CuS nanostructures is tailored by controlling the pH of the reaction media. CuS nanoflakes obtained at a pH of 7.4, transformed into nanocubes at 10, and deformed at a pH of 13. Powder X-ray diffractograms show that the CuS nanostructures are organized in a hexagonal crystal system. The +2 and -2 oxidation states of the Cu and S ions, respectively, are verified by the highresolution XPS spectra. A huge proportion of greenhouse CO2 gas was physisorbed by the CuS nanoflakes. CuS nanoflakes developed at a pH of 7.4 had a lower bandgap than CuS nanostructures developed at pH 10 and 13, resulting in a faster photocatalytic degradation of 95% crystal violet and ght. Additionally, the sodium alginate-CuS nanoflakes exhibit outstanding performance in photo-redox processes to convert ferricyanide into ferrocyanideShort Description of what will be discussed during the presentation 98% methylene blue in aqueous dye solutions, respectively, in 60 and 90 minutes when illuminated with blue light.
