The 2-vinyl-4, 5-dicyanoimidazole (Vinazene) was used as a nitrogen precursor to synthesize a promising non-precious metal (NPM) catalyst for oxygen reduction reaction (ORR). Vinazene together with an iron source was impregnated into a carbon matrix and pyrolyzed at 900°C in N2 atmosphere. The structure of the resulting Fe–N–C nanocomposite was analyzed by X-ray photoelectron spectroscopy, Raman spectroscopy...
Small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS) techniques were used to characterize the PANI-0.5-HCSA morphology in nylon blends. SAXS shows that the polyaniline (PANI) salt resides mainly in the inter-spherulitic region of the nylon host. The morphology of the conducting salt component was analyzed by SANS data and was treated by two standard models: Debye-Bueche...
