Characterization of carbon nanotubes decorated with NiFe2O4 magnetic nanoparticles as a novel electrochemical sensor: Application for highly selective determination of sotalol using voltammetry

Synthesis and characterization of NiFe2O4 nanoparticles using the hydrothermal method as magnetic catalysts for electrochemical detection of norepinephrine in the presence of folic acid

“…As can be seen from the FT‐IR spectra, the normal mode of vibration of the tetrahedral cluster (599 cm −1 ) is higher than that of the octahedral cluster (465 cm −1 ). This is due to the shorter bond length of tetrahedral cluster than the octahedral cluster …”

“…No diffraction peaks of other impurities such as α‐Fe 2 O 3 or NiO were observed. The broadness of the diffraction peaks suggests the nanosized nature of the product and the average crystallite size (t) of it was calculated to be as 40.0 nm using the Debye–Scherrer formula; t = 0.9 λ / β cos( θ ), where λ is the wavelength of the X‐ray radiation (1.54056 Å for Cu lamp), θ is the diffraction angle, and β is the full width at half‐maximum (FWHM) …”

“…The quantitative cytotoxicity test verified that NiFe 2 O 4 nanoparticles had noncytotoxicity. Moreover, NiFe 2 O 4 NPs exhibit a high surface area and low mass transfer resistance …”

The study of structural properties of carbon nanotubes decorated with NiFe2O4 nanoparticles and application of nano-composite thin film as H2S gas sensor

“…The produced mixture was dried in an oven at 100°C for 12 h. The produced substance was calcinated at 620°C for 2 h in argon atmosphere. The resulted powder was denoted as NiFe 2 O 4 -MWCNTs [25]. The structural, morphological and magnetic properties of the nano-composite were characterized by XRD, FESEM, AFM and VSM.…”

Optimization of manganese oxide amount on Vulcan XC-72R carbon black as a promising support of Ni nanoparticles for methanol electro-oxidation reaction

“…Multiwalled carbon nanotubes decorated with NiFe 2 O 4 nanoparticles were investigated as a suitable electrocatalyst for sotalol oxidation at a potential value of 500 mV (Ag/AgCl). Linear sweep voltammetry study showed two wide linear dynamic ranges of 0.5e1000 mmol L À1 with a detection limit of 0.09 mmol L À1 [26].…”
