High-quality reduced graphene oxide-nanocrystalline platinum hybrid materials prepared by simultaneous co-reduction of graphene oxide and chloroplatinic acid
Reduced graphene oxide-nanocrystalline platinum (RGO-Pt) hybrid materials were synthesized by simultaneous coreduction of graphene oxide (GO) and chloroplatinic acid with sodium citrate in water at 80°C, of pH 7 and 10. The resultant RGO-...

| description | Reduced graphene oxide-nanocrystalline platinum (RGO-Pt) hybrid materials were synthesized by simultaneous coreduction
of graphene oxide (GO) and chloroplatinic acid with sodium citrate in water at 80°C, of pH 7 and 10. The
resultant RGO-Pt hybrid materials were characterized using transmission electron microscopy (TEM), powder X-ray
diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier-transform infrared spectroscopy, and
thermogravimetric analysis. Platinum (Pt) nanoparticles were anchored randomly onto the reduced GO (RGO)
sheets with average mean diameters of 1.76 (pH 7) and 1.93 nm (pH 10). The significant Pt diffraction peaks and
the decreased intensity of (002) peak in the XRD patterns of RGO-Pt hybrid materials confirmed that the Pt
nanoparticles were anchored onto the RGO sheets and intercalated into the stacked RGO layers at these two pH
values. The Pt loadings for the hybrid materials were determined as 36.83 (pH 7) and 49.18% (pH 10) by mass
using XPS analysis. With the assistance of oleylamine, the resultant RGO-Pt hybrid materials were soluble in the
nonpolar organic solvents, and the dispersion could remain stable for several months. |
