The aim of this paper is to study the gel formation tendency in the TiO2–TeO2–SeO2 system. Telluric acid (H6TeO6), selenous acid (H2SeO3) and titanium butoxide were used as precursors dissolved in ethylene glycol. Transparent monolithic and bright yellow colored gels are situated between 40–100 mol% TiO2, up to 20 mol% SeO2 and 65 mol% TeO2. The phase transformations of the as-prepared gels heat-treated...
A series of conducting polymer complexes of poly(3-octylthiophene) and titanium dioxide (POT/TiO2) in different proportions were synthesized. X-ray diffraction patterns (XRD) indicated that the interplaner spacing of the composite samples is smaller than the pure TiO2. X-ray photoelectron spectroscopy (XPS) and IR support a chemical interaction between POT and nano-TiO2 in the complexes. Cyclic voltammetry...
