    Open Research Data
    open access

    X-ray powder diffraction patterns of samples were carried out by Philips X’Pert diffractometer, which was radiated by graphite monochromatized Cu Kα (l equal 1.540598). The operating voltage was maintained at 40 kV, the current was maintained at 30 mA and analyzed in the range from 20° to 90°. The data presented confirmed the presence of the PrBSCF...

  • Raman spectra for pyrolized natural compounds

    Open Research Data
    open access

    The presented data showcases the results of Raman spectroscopy analysis conducted on pyrolyzed natural compounds both with and without the inclusion of graphene. The study delved into four specific compounds: methylcellulose with lysine (ML), methylcellulose with lysine-graphene composite (MLG), algae (A), and algae-graphene composite (AG). Raman spectra...

  • The hydrogen evolution reaction (HER) performance of some FTO/MoS2/SnO2 electrodes

    Open Research Data
    open access

    To demonstrate the electrochemical performance of the FTO/MoS2/SnO2 for HER (hydrogen evolution reaction), the LSV (linear sweep voltammetry) was performed. The polarization curves of the obtained composite were measured in 1 M H2SO4 at room temperature with a scan rate 10 mV/s. For comparison, the LSV for the FTO, pure MoS2 and Pt plate electrode were...
