Fe-doped TiO2 nanorods with enhanced electrochemical properties as efficient photoanode materials

Hydrothermal Cobalt Doping of Titanium Dioxide Nanotubes towards Photoanode Activity Enhancement

“…Due to the various modifications of nanostructure, there are large discrepancies in photocurrent values. However, as the authors mentioned [ 64 , 65 , 66 ], introducing low amounts of chemical elements into the anatase structure promotes increasing the photoresponse. Too high doping level of TiO 2 causes a decrease in photocurrent density.…”

Fe-TiO2 Nanoparticles Synthesized by Green Chemistry for Potential Application in Waste Water Photocatalytic Treatment

“…Owing to exceptional and appropriate properties including nontoxic, excellent chemical stability, strong ultraviolet (UV) absorption, and wide band gap energy (anatase 3.2 eV and rutile 3.4 eV), titanium dioxide (TiO 2 ) is a recognized metal oxide semiconductor which could be extensively applied to diverse applications. Hence, the utilization of sustainable luminous energy like visible light or sunlight is limited, because TiO 2 can only be excited by ultraviolet light (wavelength lower than 387 nm), which occupies only 3-5% of the entire solar spectrum [5][6][7][8][9][10][11]. It is also known that high recombination of activated electron-hole pair of TiO 2 is still its major drawback that causes the restriction of practical applications, in particular, solar harvesting aspect [10,12,13].…”

One-step synthesis of magnetic-TiO2-nanocomposites with high iron oxide-composing ratio for photocatalysis of rhodamine 6G

“…Since the photocatalytic active sites are mainly located on TiO 2 instead of iron oxides [43], higher percentage of TiO 2 in magnetic-TiO 2 -nanocomposites increases the photocatalysis capability. Iron- composing benefits the photocatalytic performance of TiO 2 because transition metal ions can act as shallow charge traps in the crystal structure, inhibiting the recombination of electron-hole pairs and prolonging their lifetime [54]. Although the impacts of transition metals on TiO 2 catalytic performance strongly depend on the composing ratio and are reported to peak at low level, all the previous studies focused on the low Fe-composing ratio, normally less than 10 at.% [33,55].…”
