The present study demonstrates utilization of functionalized seaweed polysaccharide, namely agarose–gallate (Ag–GAEst) for the preparation of reduced graphene oxide (rGO) under mild reaction conditions. Ag–GAEst obtained with the lowest degree of substitution (degree of substitution (DS) = 0.45; with 1 : 0.5 w/w agarose : gallic acid) shows excellent performance compared to its high DS (1.1; with 1 : 2.0 w/w agarose : gallic acid) ester derivatives. Further, the formation of rGO was confirmed using UV–Vis, TEM, FTIR, Raman spectroscopy, elemental and XRD analysis. This study describes a new application of seaweed-derived polysaccharides.

Abstract


The present study demonstrates utilization of functionalized seaweed polysaccharide, namely agarose–gallate (Ag–GAEst) for the preparation of reduced graphene oxide (rGO) under mild reaction conditions. Ag–GAEst obtained with the lowest degree of substitution (degree of substitution (DS) = 0.45; with 1 : 0.5 w/w agarose : gallic acid) shows excellent performance compared to its high DS (1.1; with 1 : 2.0 w/w agarose : gallic acid) ester derivatives. Further, the formation of rGO was confirmed using UV–Vis, TEM, FTIR, Raman spectroscopy, elemental and XRD analysis. This study describes a new application of seaweed-derived polysaccharides.
