Abstract
Herein we present, electrodeposition of gold dendritic nanostructures (Au-DNs) at reduced graphene oxide (RGO) functionalized with β-cyclodextrins (CD). The structural features of the Au-DNs and their interfacing mechanism with RGO are characterized by UV–Visible, FESEM, EDX, XPS, XRD and Raman analysis. The growth mechanism of Au-DNs at RGO–CD support has been elucidated using FESEM measurements. The CD induces the formation and plays a crucial role in shaping the dendrite morphology of Au nanostructures at RGO–CD along with the ad layer of ammine functionalized silicate sol–gel matrix (TPDT). The combined effect of RGO and Au-DNs provoked the synergistic electrocatalytic activity towards the nitrite and glucose electrooxidation.
