چکیده

Single-crystalline TiOF(2) crystals with cubical morphology were prepared via a facile solvothermal method and their transformation to anatase TiO(2) under different calcination conditions such as pure argon, moist argon and pure hydrogen sulfide (H(2)S) was explored by using XRD/Raman/UV-Vis/SEM/TEM/SAED. The non-metal sulfur doping was successfully fulfilled and the doped TiO(2) microcubes showed the best photocatalytic H(2) evolution property.

Hydrogen Reduced Rutile Titanium Dioxide Photocatalyst

For TiO2 photocatalysts, recombination of photoexcited electrons and holes would occur in crystalline defects such as oxygen vacancies, Ti ions, and surface states. Therefore, it is believed that the density of crystalline defects should be decreased to improve the photocatalytic activity of TiO2 particles. Contrary to this common knowledge, the introduction of crystalline defects by hydrogen r...

Modified Titania Films for Photoelectrochemical Applications

TiO2 is recognized as a photocatalytic material and has been widely used because of its high functionality, long –term stability and non-toxicity. [1]However, because the band gap of pure TiO2 for anatase crystalline phase is as high as 3.2ev, TiO2 shows only high reactivity under ultraviolet light. In order to make the better use with ideal energy source, sunlight, people have tried several mo...

The effect of solvent of titanium precursor in the sol-gel process on the activity of TiO2 nanoparticles for H2 production

A modified sol-gel process has been found to significantly improve the photocatalytic activity of TiO2 nanoparticle in the process of solar hydrogen production. The surface of TiO2 nanoparticles were modified by the optimization of solvent of titanium precursor (acetic acid and/or ethanol) in the sol-gel method. A multi technique approach (SEM, XRD, FTIR, UV-DRS and TGA) was used to characteriz...
