Titanium dioxide, TiO 2, is an important photocatalytic material that exists as two main
polymorphs, anatase and rutile. The presence of either or both of these phases impacts on …

The utilization of solar irradiation to supply energy or to initiate chemical reactions is already
an established idea. If a wide-band gap semiconductor like titanium dioxide (TiO2) is …

TiO2 thin films were prepared on fused quartz by the liquid-phase deposition (LPD) method
from a (NH4) 2TiF6 aqueous solution upon addition of boric acid (H3BO3) and calcined at …

A series of TiO2 samples with different anatase-to-rutile ratios was prepared by calcination,
and the roles of the two crystallite phases of titanium (IV) oxide (TiO2) on the photocatalytic …

Nanosized titanium oxide with and without addition of lanthanum oxide is prepared by the
solution sol− gel method. Resultant gel precursor was characterized by thermal analysis and …

Titania–silica composite nanoparticles were prepared by sol–gel-hydrothermal and sol–gel
routes, respectively, and their physico-chemical and photocatalytic properties were …

A systematic study of microstructure and photocatalytic properties of lanthanide doping of
nanocrystalline mesoporous titanium dioxide is performed. The anatase-to-rutile (AR) phase …

Mixed titanium dioxide (TiO2) powders of various amorphous-anatase–rutile contents were
prepared by acid-catalyzed sol–gel method at 80° C without calcination. The physico …

Silica-modified titanium dioxides were prepared by a hydrothermal method and then
characterized by XRD, FT-IR, XPS, TEM, and UV–visible spectroscopy. The silica-modified …

Heterogeneous photocatalysis continues to be an active area of research with focus on
developing catalytic systems that can degrade toxic pollutants in the gas and aqueous …
