The photocatalytic degradation of the emerging contaminant paracetamol in aqueous solution has been studied under 1 SUN (~1000 W m−2) presence four commercial TiO2 powders, namely sub-micrometric anatase and rutile, nanometric brookite P25 (the popular anatase/rutile mixture used as a benchmark most papers). rutile powder showed low activity, whereas, interestingly, powders outperformed terms t...

The results of our multitechnique investigation performed on diindenoperylene thin films deposited on rutile TiO2(110) show island growth, with crystallites nucleating preferentially along the [110] substrate crystallographic axis. The findings evidence that the films' properties at the interface are common to those found for a number of organic molecules deposited on the same substrate, reveal...

The quasiparticle spectra in the metallic rutile and insulating monoclinic phases of VO2 are shown to be dominated by local Coulomb interactions. In the rutile phase the small orbital polarization among V 3d t2g states leads to weak static but strong dynamical correlations. In the monoclinic phase the large 3d orbital polarization caused by the VuV Peierls distortion gives rise to strong static...

Nanostructuring of surfaces and two-dimensional materials using swift heavy ions offers some unique possibilities owing to the deposition of a large amount of energy localized within a nanoscale volume surrounding the ion trajectory. To fully exploit this feature, the morphology of nanostructures formed after ion impact has to be known in detail. In the present work the response of a rutile TiO...

The interaction of water with TiO2 is crucial to many of its practical applications, including photocatalytic water splitting. Following the first demonstration of this phenomenon 40 years ago there have been numerous studies of the rutile single-crystal TiO2(110) interface with water. This has provided an atomic-level understanding of the water-TiO2 interaction. However, nearly all of the prev...

A simple and steerable method was adopted to synthesize well-distributed rutile TiO2 nanobundles on reduced graphene oxides through two-step hydrothermal methods. The rutile TiO2-RGO composites were used as the anode materials in lithium ion batteries for investigation, which had an original morphology and a reversible capacity of 300 mA h g(-1) at 0.6 C and 200 mA h g(-1) at 1.2 C after 500 cy...

A new type of nonstoichiometric rutile titanium dioxide (TiO2) film with around 15 at% oxygen vacancies homogeneously distributed throughout the bulk was prepared. The resultant films, when used as a photoelectrode, showed a photoelectrochemical water splitting activity 1.7 times that of stoichiometric TiO2 at a bias of 0.9 V vs. Ag/AgCl. This is believed to result from the synergistic effect o...

A photoelectrochemical (PEC) detection platform was built based on the branched rutile/anatase titanium dioxide (RA-TiO2) electrode. Theoretical calculations proved that type-II band alignment of rutile and anatase could facilitate charge separation in The self-generated electric field at interface two phases can enhance electron transfer efficiency Carboxylated CdTe quantum dots (QDs) were app...

In order to provide important details concerning the adsorption reactions of Sr, batch and a set both ex situ in Grazing Incidence X-ray Absorption Fine Structure (GIXAFS) experiments were completed on powdered TiO2 rutile(110), reacted with either SrCl2 or SrCO3 solutions. sorption capacity for strontium (Sr) ranges from 550 ppm (SrCl2 solutions, second kinetics) 1400 (SrCO3 first kinetics), r...

Anatase/rutile mixed titania nanotubes (TiO2 NTs) precipitated with gold nanoparticles (Au NPs), i.e. Au/TiO2, have been synthesized and investigated on visible photocatalysis properties. A deposition-precipitation (DP) method was adopted to reduce the gold precursor to Au NPs within the preformed TiO2 NTs by the emulsion electrospinning technique. The optimal visible photocatalytic activity wa...
