Graphene-polypyrrole (GP) nanocomposites were synthesized by a wet-way protocol using graphite bisulfate (GBS) precursor. Consequently, GBS, type of intercalation compound, was prepared in the presence concentrated sulfuric acid potassium periodate oxidizer. Three different types precursor with particle sizes <50 μm, ≥150, ≤830 and ≤2000 μm used for this purpose. It found that Raman spectra ...

In this work, graphite intercalation compounds (GICs) were synthesized using three different oxidizers: (NH4)2S2O8, K2S2O8, and CrO3 with without P2O5 as a water-binding agent. Furthermore, the samples obtained heat-treated at 800 °C. Specimens characterized by optical microscopy, Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), scanning electr...

Transition metal sulfides are scientifically and technologically important materials. This review summarizes recent progress on the synthetic fabrication of transition metal sulfides nanocrystals with controlled shape, size, and surface functionality. Special attention is paid to the case of MoS2 nanoparticles, where organic (surfactant, polymer), inorganic (support, promoter, doping) compounds...
