“…Two broad peaks at around 26 ∘ and 44 ∘ could be attributed to the initial graphite indicating that the oxidation of graphite was incomplete. In fact, a similar result is also obtained in reported papers [35,36]. After reduced by ascorbic acid, the material does not show the peak at 11.3 ∘ , and the weak and broad reflection peak at 25.8 ∘ corresponds to the relative short-range order structures in disordered stacked rGO [37], which indicates the successful reduction of GrO.…”

The synthesis of magnetic iron oxide/reduced graphene oxide (Fe 3 O 4 /rGO) and its application to the electrochemical determination of paracetamol using Fe 3 O 4 /rGO modified electrode were demonstrated. The obtained materials were characterized by means of X-ray diffraction (XRD), nitrogen adsorption/desorption isotherms, X-ray photoelectron spectroscopy (XPS), transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FTIR), and magnetic measurement. The results showed that Fe 3 O 4 /rGO composite exhibited high specific surface area, and its morphology consists of very fine spherical particles of Fe 3 O 4 in nanoscales. Fe 3 O 4 /rGO was used as an electrode modifier for the determination of paracetamol by differential pulseanodic stripping voltammetry (DP-ASV). The preparation of Fe 3 O 4 /rGO-based electrode and some factors affecting voltammetric responses were investigated. The results showed that Fe 3 O 4 /rGO is a potential electrode modifier for paracetamol detection by DP-ASV with a low limit of detection. The interfering effect of uric acid, ascorbic acid, and dopamine on the current response of paracetamol has been reported. The repeatability, reproducibility, linear range, and limit of detection were also addressed. The proposed method could be applied to the real samples with satisfactory results.

AbstractA simple method based on potentiostatic polymerization was developed for the preparation of ternary manganese oxide-based nanocomposite films. The ternary nanocomposites, which were characterized using x-ray diffraction spectroscopy and x-ray photoelectron spectroscopy, showed that the manganese oxide within the film consisted of MnO 2 and Mn 2 O 3 . Electrochemical measurements showed that the ternary nanocomposite electrode exhibited high specific capacitance (up to 320.6 F/g), which was attributed to the morphology of a polypyrrole/graphene/manganese-oxide (PPy/GR/MnO x ) ternary nanocomposite. The experimental approach maximized the pseudocapacitive contribution from redox-active manganese oxide (MnO x ) and polypyrrole (PPy), as well as the electrochemical double layer capacitive (EDLC) characteristic from graphene (GR) sheets. Long cyclic measurements indicated that the specific capacitance of the ternary nanocomposite film could retain 93% of its initial value over 1,000 charge/discharge cycles, in the potential range of -0.2 to 0.7 V vs. silver/silver chloride electrode (Ag/AgCl).
