Synthesis of a graphene–carbon nanotube composite and its electrochemical sensing of hydrogen peroxide

Graphene-Multiwalled Carbon Nanotube Hybrids Synthesized by Gamma Radiations: Application as a Glucose Sensor

“…However, in the present reaction, at the time of reduction (during irradiation) MWCNTs are introduced between the graphene layers, and they avoid stacking up of graphene layers,therefore interlayer spacing does not show significant changes. It is worth noting that the data for GO and fMWCNTs are in good agreement with the previous reports [28,46]. The electronic and crystallographic structures of the samples were evaluated by micro-Raman spectroscopy.…”

“…Electrical conductivity of CNTs is also affected 2 Journal of Nanotechnology due to the nonuniform contact and discontinuities between all the CNTs in the heterogeneous structure [21], thereby limiting their application as sensors [17,[22][23][24]. Therefore, an intelligent and unique graphene-carbon nanotube hybrid film, consisting of CNTs connected perpendicularly to graphene layers, could overcome some of the shortcomings and limitations of individual components [25][26][27][28][29]. Thus, many efforts have been made so as to obtain graphene-carbon nanotube hybrids by different methods of synthesis [25][26][27][28][29][30][31][32].…”

Synthesis of reduced graphene oxide intercalated ZnO quantum dots nanoballs for selective biosensing detection

“…Previous studies have shown that GO-MWCNTs nanocomposite resulted in large active surface area and fast electron transfer ability. [11,12] Unfortunately, the composite architecture formed by pristine freeze-drying aqueous solutions of GO and MWCNTs exhibited weak mechanical and dimensional instability in some cases, especially as electrode materials in a solution. Ni foam with high porosity and large specific surface area is widely utilized as the outstanding supporting matrix for loading active functional materials.…”
