RETRACTED: Effects of N Doping on Structure and Improvement Photocatalytic Properties of Anatase TiO2 Nanoparticles

Shape transitions of epitaxial islands during strained layer growth: anatase TiO2(001) on SrTiO3(001).

Extended annealing in UHV causes the surface region of SrTiO3(001) to become enriched with TiO2, resulting in the formation of epitaxial islands of anatase TiO2(001). The islands are studied using UHV scanning electron microscopy (SEM), which reveals the changes in morphology during growth induced by misfit strain. Starting from a square island, two types of shape transition are observed. In th...

effects of n doping on structure and improvement photocatalytic properties of anatase tio2 nanoparticles

in order to improve uv and visible lights photocatalytic activities of the pure anatase tio2, a novel and efficient n-doped tio2 photocatalyst was prepared by sol-gel method. n-doped titania is prepared using triethylamine (with difference molar ratios) as the nitrogen source. the crystalline structure, morphology, particle size, absorbance and band-gap and chemical structure of n-doped tio2 wa...

Influence of nitrogen doping on the defect formation and surface properties of TiO2 rutile and anatase.

Nitrogen doping-induced changes in the electronic properties, defect formation, and surface structure of TiO2 rutile(110) and anatase(101) single crystals were investigated. No band gap narrowing is observed, but N doping induces localized N 2p states within the band gap just above the valence band. N is present in a N(III) valence state, which facilitates the formation of oxygen vacancies and ...
