Enzymeless electrochemical detection of hydrogen peroxide using NiO octahedron decorated 3D graphene hydrogel.

ABSTRACT: Nowadays, electrochemical biosensors have gained extensive consensus to detect a wide variety of analytes such as hydrogen peroxide (H₂O₂), glucose, dopamine, uric acid, and so on. However, the detection of H₂O₂ is more and more important because H₂O₂ plays a vital role in our daily life. Hence, a new nonenzymatic H₂O₂ biosensor was developed by decorating NiO octahedrons on the 3-dimensional graphene hydrogel (3DGH). The NiO octahedrons were prepared using a mesoporous silica SBA-15 as a hard template. Then, different amounts of NiO octahedrons self-assembled with 3DGH during hydrothermal method. The performance of different prepared nanostructures as H₂O₂ biosensors electrodes wa
