Synthesis and characterization of long wavelength visible-light absorption Cu-doped TiO2 nanomaterials with well-controlled properties such as size, composition, morphology, and crystal phase have been demonstrated in a single-step flame aerosol reactor. This has been feasible by a detailed understanding of the formation and growth of nanoparticles in the high-temperature flame region. The impo...

Ternary erbium doped BiVO4/TiO2 complexes are synthesized by means of a simple impregnation method with good photoactivities under sun-like excitation for the degradation of phenol. From the structural and morphological characterization it has been stated that the presence of Er induces a slight stabilization of the tetragonal phase probably due to its incorporation in the BiVO4 lattice. Theref...

The dehydrogenation properties of LiAlH4 doped with different Ti precursors (Ti, TiO2, and TiCl3) via ball milling are investigated. The results not only show significant decreases in the decomposition temperatures (Tdec) and activation energies (EA) of the first two dehydrogenation reaction steps of LiAlH4 by doping with TiO2 or TiCl3, but also reveal how each Ti precursor affects the dehydrog...

In this work, TiO2 /SiO2 (pure anatase), and TiO2 /SiO2 (anatase/rutile) nano-photocatalysts are prepared by using sol-gel method and control of acidity. The particles size is calculated using Scheerer, s equation and is estimated to be around 7-15 nm. In order to improve the photocatalytic activity of TiO2 /SiO2 ,1% (wt) platinum particles are loaded on both catalysts using photoreductive meth...

In this communication, a new photoelectrochemical aptasensor with Au nanoparticle functionalized self-doped TiO2 nanotube arrays (Au/SD-TiO2 NTs) as the core sensing unit and aptamers as the recognition unit was set up to accomplish the sensitive and selective detection of kanamycin with the lowest detection limit of 0.1 nM.

Transition metal doping into the TiO2 lattice can expand the response of these metal oxide nano particles to the visible region. In view of this, Mo ion is doped into the TiO2 lattice in order to understand the mechanism of its photo response. The prepared photocatalysts were characterized by X-ray diffraction, UV–Visible absorption spectroscopy, UV–Visible diffuse reflectance spectroscopy, SEM...

The solid-state hydrolysis and air calcination of aluminum-doped TiCl3 leads to crystalline anatase TiO2 that is stable on heating to 1000 degrees C, in contrast to control studies with related AlCl3 and TiCl3 physical mixtures that produce rutile TiO2 under the same conditions.

Establishing an S-scheme heterojunction is a promising method for increasing the photocatalytic activity of synthetic materials. In this work, using thermal decomposition methods, nitrogen-doped g-C3N5/TiO2 photocatalysts have been synthesized...
