Polyethyleneimine-modified super paramagnetic Fe3O4 nanoparticles: An efficient, reusable and water tolerance nanocatalyst.

Polyethyleneimine-modified super paramagnetic Fe3O4 nanoparticles: An efficient, reusable and water tolerance nanocatalyst.

A novel magnetically immobilized polyethyleneimine (PEI) fabricated by covalently anchoring on silica coated Fe3O4 nanoparticles (PEI@Si-MNPs) was prepared. The synthesized catalyst was characterized by Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM). The immobili...

Oxygen reduction reaction on Pt/C at the presence of super paramagnetic of Fe3O4 nanoparticles for PEMFCs

In this paper the role of super paramagnetic iron oxide nanoparticles (SPI) on Platinum nanoclusters on activated carbon (Pt/C) for electrocatalytic oxygen reduction reaction was considered. Four composites of Pt/C and super paramagnetic iron oxide nanoparticles were prepared with the same total composites weight and different loading of Pt/C (1.2, 0.6, 0.4 and 0.3 mg ). The composite attached ...

Preparation and characterization of PEG/Dextran coated superparamagnetic Iron Oxide (Fe3O4) nanoparticles for biomedical applications

Recent progress in nanotechnology and electrochemical methods can be applied to fine control of the size, crystal structure, and surface properties of iron oxide nanoparticles. Here we appliedcathodic electrochemical deposition (CED) as an efficient and effective tactic for synthesisand double coating of surface of superparamagnetic iron oxide nanoparticles (SPIONs). In first step, bare Fe3O4 n...
