Effect of Cu doping on the anatase-to-rutile phase transition in TiO2 photocatalysts: theory and experiments /
(Elsevier, 2019-01-22)
This paper shows that incorporation of Cu inhibits the anatase to rutile phase transition at temperatures above
500 °C. The control sample, with 0% Cu contained 34.3% anatase at 600 °C and transitioned to 100% rutile ...
Ternary chalcogenides and their composites with titanium dioxide for photocatalytic applications /
(IT Sligo, 2021)
This thesis addresses the preparation of semiconductor nanomaterials and their
composites with ternary chalcogenides (TC) for photocatalytic applications. Rapid
depletion and ever-increasing demand for fossil fuels ...
Advances in catalytic/photocatalytic bacterial inactivation by nano Ag and Cu coated surfaces and medical devices /
(Elsevier, 19 July 20)
The design, synthesis, fundamentals and evaluation of 2D/3D antimicrobial surfaces are addressed in detail in the current review. Recent advances in the antimicrobial mechanism, kinetics and properties of Ag, Cu and Ag-Cu ...
Black TiO2 Nanomaterials: A Review of Recent Advances /
(Elsevier, 2018-02-02)
Recently reported black TiO2 nanomaterials are the unequivocally accepted sun light harvesters which facilitate
the maximum solar energy absorption from ultraviolet (UV) to infrared (IR) region of the solar spectrum due ...
UV and Visible Light-Driven Production of Hydroxyl Radicals by Reduced Forms of N, F, and P Codoped Titanium Dioxide /
(MDPI, 2019-06-06)
The photocatalytic activities of reduced titanium dioxide (TiO2) materials have been
investigated by measuring their ability to produce hydroxyl radicals under UV and visible light
irradiation. Degussa P25 TiO2 was doped ...

(IOP Publishing, 2020)
This work outlines an experimental and theoretical investigation of the effect of molybdenum (Mo)
doping on the oxygen vacancy formation and photocatalytic activity of TiO2. Analytical techniques such
as x-ray diffraction ...
New insights into the efficient charge transfer of ternary chalcogenides composites of TiO2 /
(Elsevier, 2020-10-05)
A two-step solvothermal synthesis was adopted to prepare AgXSe2-TiO2 (X = In, Bi) composites. DFT study of
the pristine parent samples showed the formation of the hexagonal phase of AgBiSe2, and tetragonal phase of
AgInSe2 ...
Cu-Doped TiO2: Visible Light Assisted Photocatalytic Antimicrobial Activity /
(MDPI, 2018-10-26)
Surface contamination by microbes is a major public health concern. A damp environment is
one of potential sources for microbe proliferation. Smart photocatalytic coatings on building surfaces
using semiconductors like ...
Anatase to rutile transition in titanium dioxide photocatalytic nanomaterials /
(2019)
Anatase and brookite are both considered metastable phases and transition irreversibly into the thermodynamically stable rutile phase at elevated temperatures (600-700°C in pure synthetic TiO2). Anatase TiO2 is widely ...
Modification of TiO2 with hBN: high temperature anatase phase stabilisation and photocatalytic degradation of 1,4-dioxane /
(IoP, 2019)
This paper examines the modification of anatase TiO2 with hexagonal boron nitride (hBN) and the impact this coupling has on the temperature of the anatase to rutile phase transition and photocatalytic activity. All samples ...
