Decoration of GO with Fe spinel-Naf/DMAP: an electrochemical probe for sensing H₂O₂reduction

Abstract

We herein report the preparation of graphene oxide decorated with Fe spinel (Fe3O4)-Naf/DMAP for an unprecedented and highly selective non-enzymatic electrochemical sensing of hydrogen peroxide.

Facile Green Approach for Developing Electrochemically Reduced Graphene Oxide-Embedded Platinum Nanoparticles for Ultrasensitive Detection of Nitric Oxide

“…From the above equation, the electron transfer coefficient was calculated using the Laviron equation eq where dln j a /d E is the slope inverse value obtained from the Tafel plot of E pa vs log (ν) (Figure S6). The calculated electron transfer coefficient (α) is 0.257.…”

Graphene quantum dots incorporated NiAl2O4 nanocomposite based molecularly imprinted electrochemical sensor for 5-hydroxymethyl furfural detection in coffee samples

“…NiAl 2 O 4 with an easy and low-cost preparation technique has low conductivity in terms of electrochemical applications although it has biocompatibility and high durability. However, this low electrical conductivity can be eliminated by making complexes with various materials, such as graphene, 18 graphene oxide 19 and carbon nanotubes. 20 This situation can provide the reduction of band gap and high conductivity.…”
