Nanosized fibrous cerium(IV) hydrogen phosphate membrane, Ce(HPO₄)₂·2.9H₂O (nCeP_f), was prepared and characterized by chemical, XRD (X-ray diffraction), TGA (thermogravimetric analysis), SEM (scanning electron microscopy) and TEM (transmission electron microscopy). Novel supported nanofibrous Ce(IV) phosphate/polyiondole nanocomposite membranes were prepared via in-situ chemical oxidation of the monomer that was promoted by the reduction of Ce(IV) ions present in the inorganic matrix. The presence of Ce(IV) ions allows redox reactions necessary to oxidative polymerization to occur. The resultant material was characterized by TGA, elemental (C, H, N) analysis and FT-IR (Fourier transform spectroscopy). SEM images of the resulting nanocomposite reveals a uniform distribution of the polymer on the inorganic matrix. Amount of polyindole polymer present in the composite is found to be ~ 7.0%.
