Functionalization of chitosan by metformin, nickel metal ions and magnetic nanoparticles as a nanobiocomposite for purification of alkaline phosphatase from hen's egg yolk
“…In the FTIR spectrum of NiCuFe 2 O 4 @MCM-48/GO/PρPD, the broad peak observed in the 3400–3750 cm −1 region is assigned to the stretching vibration mode of hydroxyl groups in GO and the stretching mode of the N–H of the secondary amine group in the polymer chain of PρPD. Two peaks are also visible at approximately 1314 and 1228 cm −1 , which correspond to the stretching vibrations of the quinone imine units (–C–N– and C–N)) 10 , 20 , 48 – 51 . Figure 2 Fourier-transform infrared (FTIR) spectra of samples.…”
In this study, a new nanocomposite was created by combining copper-doped nickel ferrite (NiCuFe2O4) nanoparticles with MCM-48 (Mobil Composition of Matter No. 48) on a graphene oxide (GO) substrate functionalized with poly(ρ-phenylenediamine) abbreviated as (PρPD). This nanocomposite was developed to investigate its potential for enhancing the function of a supercapacitor in energy storage. Following NiCuFe2O4@MCM-48 preparation, Hummer’s technique GO was applied. In-situ polymerization of NiCuFe2O4@MCM-48/GO nanoparticles with ρ-phenylenediamine (ρPD) in the presence of ammonium persulfate (APS) produced PρPD, a conductive polymer. Structural characterization of the nanocomposite includes FTIR, XRD, VSM, TGA-DTG, EDX, and FE-SEM. Results from BET indicate a pore size increase of up to 5 nm. Fast ion penetration and higher storage in capacitor material are explained by this. Additionally, the nanocomposite’s electrochemical performance was evaluated using GCD and CV tests. The NiCuFe2O4@MCM-48/GO/PρPD nanocomposite has a specific capacitance of 203.57 F g−1 (1 A g−1). Furthermore, cyclical stability is essential for energy storage applications. The nanocomposite retains 92.5% of its original capacitance after 3000 cycles, indicating outstanding electrochemical stability.
