Nickel-cobalt nanostructures coated reduced graphene oxide nanocomposite electrode for nonenzymatic glucose biosensing

Carbon nanotube template synthesis of hierarchical NiCoO2 composite for non-enzyme glucose detection

“…As reported that, theNiOOH can be used as heterogeneous catalystsforglucose oxidation toyieldglucolactone. [23,[34][35][36] When applying a potential above400 mV to the nickel electrode, the Ni(III)species are produced on the electrode surface and then oxidizes glucose to generate Ni(II) species, producing the glucolactone, simultaneously, according to the following equation (2).…”

Controllable preparation of multi-dimensional hybrid materials of nickel-cobalt layered double hydroxide nanorods/nanosheets on electrospun carbon nanofibers for high-performance supercapacitors

“…It has been proven that hybrid structures of Ni-Co LDHs and carbonaceous materials, such as CNT/Ni-Co oxides composites [25], reduced graphene oxides/Ni-Co nanostructures [26,27], glassy carbon/Co-Ni films [28], can greatly contribute to the optimization of electrode properties with better rate/cycling stability and higher specific capacitance. Salunkhe et al developed nickel-cobalt binary metal hydroxide nanorods coated multiwalled carbon nanotube hybrid material through a chemical synthesis method [29].…”

Multi-wall carbon nanotube–NiO nanoparticle composite as enzyme-free electrochemical glucose sensor

“…The surface coverage of electroactive substance ( *) of 10% NiO-MWCNT/CPE was calculated as 1.5629 × 10 −6 mol cm −2 , using the Faraday's law [Q = nFA *], where Q is the integration charge of the reduction peak (0.010556 C), A is the area of the electrode (0.07 cm −2 ), n is the number of electrons transferred and F is the Faraday constant. The average value of * calculated was larger than Ni-Co NSs/RGO/GCE 8.99 × 10 −8 mol cm −2 [44]. These results could be attributed to the large specific surface area of the 10% NiO-MWCNT/CPE.…”
