Polymer nanocomposites: structure and synthesis the electrochemical method has been used for the synthesis fe 3 o 4-pani nanoparticles synthesis by aniline. The activity is mainly correlated to the larger absorptions around 496nm and 563nm wavelengths by co-doped ti02 nanoparticles than fe doped ti02 nanoparticles which possibly absorb k496nm key words: cr and fe co-doped ti02, nano-particles, hydrothermal synthesis method, photocatalysts. C liu et al, reported the formation of three dimensional mesoporous ca oxide nanoparticles prepared by hydrothermal method they used different wetting agent like ctab, p123 and peg to manufacture new morphological constructions of nanoparticles.
The exsolution of metallic nanoparticles that occurred in situ during operation was found to coincide with a dramatic (absolute) drop in the steam electrolysis (that is, water splitting) onset potential, from −121 v for the undoped perovskite to −098 v for the fe-doped perovskite and further down to −063 v for the ni-doped perovskite 42. Fe-doped tio2 was prepared by hydrothermal treating ti peroxide sol with different amount of iron nitrate fe ions can enter tio2 lattice by substituting ti4+ ions, which significantly affect the crystallinity and morphology of tio2 nanoparticles. The proposed one-pot synthesis procedure might facilitate the incorporation of fe 3+ and formation of heterojunctions between tio 2 and iron oxide phases during the transformation of titanium precursor to tio 2 which might favor the charge separation in the catalysts and further improve the photocatalytic activity.
