Cerium-Doped Zirconium Dioxide, a Visible-Light-Sensitive Photoactive Material of Third Generation.
The dispersion of small amounts of Ce(4+) ions in the bulk of ZrO2 leads to a photoactive material sensitive to visible light. This is shown by monitoring with EPR the formation and the reactivity of photogenerated (λ > 420 nm) charge carriers. The effect, as confirmed by DFT calculations, is due to the presence in the solid of empty 4f Ce states at the mid gap, which act as intermediate levels...
متن کاملVisible-light Photocatalyst - Nitrogen-doped Titanium Dioxide -
A new photocatalyst, known as nitrogen-doped TiO2 (TiO2-xNx), yielding high reactivity under visible light irradiation, together with high potential for mass-productivity, has been developed by using a highly time-efficient development technique that combines computational materials design with experimental syntheses. Under visible light irradiation, TiO2-xNx films and powders exhibit significa...
متن کاملA visible light-responsive iodine-doped titanium dioxide nanosphere.
I-doped titanium dioxide nanospheres (I-TNSs) were synthesized via a two-step hydrothermal synthesis route, their potential for the efficient utilization of visible light was evaluated. The prepared anatase-phase I-TNSs had a bimodal porous size distribution with a Brunauer-Emmett-Teller surface area of 76 m2/g, a crystallite size of approximately 14 nm calculated from X-ray diffraction data, a...
متن کاملThe visible spectrum of zirconium dioxide, ZrO2.
The electronic spectrum of a cold molecular beam of zirconium dioxide, ZrO(2), has been investigated using laser induced fluorescence (LIF) in the region from 17,000 cm(-1) to 18,800 cm(-1) and by mass-resolved resonance enhanced multi-photon ionization (REMPI) spectroscopy from 17,000 cm(-1)-21,000 cm(-1). The LIF and REMPI spectra are assigned to progressions in the Ã(1)B(2)(ν(1), ν(2), ν(3))...
