This work presents a simple green approach for the chemical synthesis of cobalt oxide nano hexagons (Co3O4 NHs) with an average size of 160±40 nm incorporated graphene nanosheets (GR). The techniques used to confirm the formation of GR−Co3O4 NHs are transmission electron microscopy (TEM), energy‐dispersive X‐ray spectroscopy (EDX), and X‐ray diffraction spectroscopy (XRD). The dopamine (DA) sensor...
In this study, we show that acid yellow 9 (4-amino-1-1′-azobenzene-3,4′-disulfonicacid, AY) is a good stabilizing agent for multi-walled carbon nanotubes (MWCNTs). MWCNTs dispersed in AY solution was remained stable about three months and even remained stable after centrifugation at 10,000rpm for 30min. Using MWCNTs/AY dispersion, thin-films were prepared on indium tin oxide coated glass electrode...
