Introducing chemical interaction between functional groups/polar sites on the host with PS is emerging as a more effective approach for caging sulfur species.[5] Recent reports found that using functionalized carbon[6,7] and m...

The paper details with of the preparation and physicochemical characterisation of nanoand microstructured TiO2 doped with Fe and Co produced by the sol-gel method using titanium alkoxide as the precursor of titania as well as iron or cobalt nitrates as dopant sources. Fe and Co doped TiO2 materials were successfully prepared with two different methods. The effect of the dopant type on the synth...

A mixture of graphene oxide (GO) and TiO2 nanocomposites was reduced photocatalytically by UV-irradiation and applied as interfacial layer between a fluorine doped tin oxide (FTO) layer and a nanocrystalline TiO2 film. Impedance spectra implied a decreased back-transport reaction of electrons. The graphene–TiO2 interfacial layer effectively reduced the contact between I 3 ions in the electrolyt...

TiO2-based materials are considered to be the promising anodes of sodium-ion batteries (NIBs) because their high safety and good stability. However, low specific capacity operating voltage plateau impose a severe challenge for energy density batteries. Herein, interconnected micro-sheets consisting carbon nanotubes sulfur doped TiO2 (CNT/S-TiO2) synthesized via an ultrasonic process subsequent ...

Photocatalytic degradation of organic compounds requires photoexcited holes with strong oxidative power in the valence band (VB) of semiconductors. Although numerous types of doped semiconductors, such as nitrogen-doped TiO2, have been studied as visible-light-sensitive photocatalysts, the quantum yields of these materials were very low because of the limited oxidation power of holes in the nit...

Visible-light-responsive tubular N-doped TiO2 nanocrystallites were synthesized via an environment-conscious solvothermal treatment of protonated titanate nanotubes in an NH4Cl/ethanol/water solution.

Gas-phase photocatalysis using titanium dioxide (TiO2) has been regarded as an attractive technology for the control of VOC emissions. However, TiO2 requires ultraviolet irradiation exceeding the bandgap energy of 3.0 eV (wavelength < 400 nm), hence effectively eliminating the utilization of solar and interior lighting as a source of photo-activation energy. Recently, a number of studies have d...

conclusions according to the results, it can be concluded that the titanium catalyst doped with iron (fe+3-tio2) processes is an appropriate method for reducing atrazine in polluted water resources. results the results demonstrated that the atrazine removal rate increased by decreasing the initial atrazine concentration and the maximum rate of atrazine removal (41.72%) was at ph = 11, atrazine ...
