Novel synergistic combination of Al/N Co-doped TiO2 nanoparticles for highly efficient dye-sensitized solar cells

Synergistic Effects of Co-Doping on Photocatalytic Activity of Titanium Dioxide on Glucose Conversion to Value-Added Chemicals

“…Also, the presence of nitrogen dopant provides the N surface state which enhances the photocatalytic activities . On the other hand, the metal or metalloid dopant has been effective on a smaller scale to become a center of charge recombination which resulted in enhancement of the photocatalytic activity of photocatalysts., Combination of nitrogen with other dopants was studied to modify photocatalysts for enhancement of visible light absorption and reduction of charge recombination − and utilized in different applications such as antibacterial activity, , dye degradation, , gaseous adsorption, hydrogen production, − dye-sensitized solar cells, and photoelectrochemistry. , Increased performance of the co-doped photocatalysts is proposed to be due to the synergistic effects of the combined co-dopants on physicochemical properties of the photocatalysts …”

High-Efficient Photocatalytic Performance under Visible Light of Functionalized TiO2 Nanofibers via Steam and Pressure Co-Modification

“…On account of less than 5% of UV light in the solar pectrum, tremendous works have been conducted to extend the spectral response range of TiO 2 in the visible region, such as heterojunction, 3 surface sensitization, 4 noble metal deposition, 5 and doping foreign elements. 6 Therein, surface sensitization is the most simple and effective pathway to widen the adsorption spectrum with high energy conversion efficiency, which has been widely used in solar cells, environmental remediation, photosynthesis, water splitting, and so forth. 4,7,8 In a typical photocatalytic process for dye-sensitized TiO 2 , fast electron transfer (ET) from the surface-bound chromophores to the conduction band of TiO 2 could be obtained under visible-light irradiation, thus resulting in efficient reduction of oxygen for the formation of reactive oxygen species (ROS), such as superoxide anion radical (O 2…”

“…TiO 2 has been extensively selected as a preferred material for environmental remediation owing to its chemical stability, low cost, high durability, nontoxicity, photocorrosion resistance, and excellent biocompatibility. , However, the inherent deficiency of wide band gap (3.2 eV), which indicates that TiO 2 only could be excited by UV light, restricts its photocatalytic efficiency and practical application.
