Preparation and photodeposition of Fe–S/TiO2@PEG nanoparticles for methylene blue and Evans blue

Improvement of the photoelectric dye sensitized solar cell performance using Fe/S-TiO2 nanoparticles as photoanode electrode

A sulfur nanoparticles-incorporated iron-doped titanium oxide (Fe/TiO2) with different ratio was successfully synthesized by photolysis method and utilized as effective photoanode in dye sensitized solar cell (DSSC) application with N719 dye. The photolysis method was contained the irradiation of the Fe, S and Ti mixture solution with 15 W source irradiation, and then calcined the formed precipitate. The DSSCs fabricated with Fe/S-TiO2 photoanode appeared an improved solar-to-electrical energy conversion efficiency of 6.46, which more than pure TiO2 (3.43) below full sunlight illumination (1.5 G). The impact of Fe content on the total efficiency was also inspected and the Fe content with 6% S-TiO2 was found 5 wt%. Due to the improved the efficiency of solar cell conversion of Fe/S-TiO2 nanocomposite, it should be deemed as a potential photoanode for DSSCs with high performance.

Synthesis of nitrogen and terbium co-doped TiO2 nanocrystals with enhanced photocatalytic activity for AO7 degradation under visible-light radiation

TiO2 nanocrystals co-doped with nitrogen and terbium exhibited extended light absorption, improved charge separation efficiency, and enhanced AO7 adsorption efficiency, giving rise to enhanced AO7 degradation activity which was 2× better than undoped TiO2 nanocrystals.
