An Electrochemical Sensor Based on Nickel Oxides Nanoparticle/ Graphene Composites for Electrochemical Detection of Epinephrine

The combination of graphene and nickel oxide nanoparticles yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. In cyclic voltammetry studies, in the presence of epinephrine, nickel oxide / graphene  composite modified electrode shows a significantly higher current response for epinephrine oxidation. Based on differenti...

A high-performance reduced graphene oxide/ZnCo layered double hydroxide electrocatalyst for efficient water oxidation.

Tailoring high performance, stable, and earth-abundant electrocatalysts for water oxidation is of fundamental importance for the development of promising energy conversion and storage technologies. In this work, we report a remarkably simple and efficient approach for the preparation of ZnCo-layered double hydroxides and reduced graphene oxide (RGO/ZnCo-LDH) nanocomposites via a facile one-pot ...

Preparation and Characterization of Reduced Graphene Oxide Doped in Sol-Gel Derived Silica for Application in Electrochemical Double-Layer Capacitors

In this study, a new graphene ceramic composite (GCC) was prepared based on the reduced grapheneoxide (rGO) doped in sol-gel derived silica. The GCC was prepared by dispersing rGO nanosheets intothe sol-gel precursors containing methyl triethoxysilane, methanol and hydrochloric acid solution.During an acid catalyzed hydrolyze reaction and gelation proc...

Quasireversible Process of Dopamine on Copper-Nickel Hydroxide Composite/Nitrogen Doped Graphene/Nafion Modified GCE and Its Electrochemical Application

Cu-Ni(OH)2/N-GR/Nafion/GCE has been prepared by electrodeposition and activation with NaOH. The proposed modified GCE was studied by electrochemical methods. It is found that dopamine shows favorable redox cyclic voltammetric response on the proposed modified GCE with peak separation of 25 mV and large current compared with on single-component modified GCE. The kinetic of electrode process has ...
