Hydroxylation of Rutile TiO$_2$ (110) Surface Enhancing Its Reducing Power for Photocatalysis [PDF]
The Journal of Physical Chemistry C 119, 1451-1456 (2015), 2015 Hydroxylation of the rutile TiO$_2$ (110) surface has attracted much attention as the excess unpaired electrons introduced by hydroxyls play a critical role in surface chemistry and photocatalysis process of this material. In this work, based on density functional theory calculations with the Hubbard U correction, the electronic structures of the ...

Influence of Defects on Photoconductivity and Photocatalytic Activity of Nitrogen-Doped Titania [PDF]
Appl Magn Reson (2017) 48: 335, 2016 Samples of nitrogen-doped titanium dioxide (anatase, $0.2 \leq N \leq 1.0~wt\%$) prepared by the sol-gel method were investigated using X-band EPR spectroscopy, photoconductivity and photocatalysis measurements. $N\bullet$ and $NO\bullet$ paramagnetic defects in N-TiO2 have been observed; their concentrations and spin-Hamiltonian parameters were ...

Promising Compounds From for Cancer Metastasis Chemoprevention
Integrative Cancer Therapies, 2017 Most of the present anticancer drugs are highly cytotoxic and focus mainly on killing tumor cells rather than slowing the progress of cancer metastasis. Evidence has been reported that bridges the mechanisms of inflammation and tumor invasion. Therefore,

TiO2 Nanocrystals Grown on Graphene as Advanced Photocatalytic Hybrid Materials [PDF]
, 2010 Graphene/TiO2 nanocrystals hybrid is successfully prepared by directly growing TiO2 nanocrystals on graphene oxide (GO) sheets. The direct growth of nanocrystals on GO sheets was achieved by a two-step method, in which TiO2 was coated on GO sheets by ...
