TiO 2-based thin films and nanomaterials have been fabricated via physical and solution-
based techniques by various research groups around the globe. Generally, most …

In this work, visible light total reflective SiO 2@ TiO 2 core-shell catalyst was synthesized by
atomic layer deposition (ALD). This core-shell catalyst processing a total reflection character …

Defective titanium dioxide (TiO2) is of much significance due to its improved visible light
photoreactivity. Generally, the existence of defects leads to imperfections in the crystal …

Photocatalysis has been regarded as one of best solutions to using the sunlight to produce
hydrogen from water and to removing organic pollutants from the environment, and titanium …

In reduced TiO2, electronic transitions originating from the Ti3+-induced states in the band
gap are known to contribute to the photoabsorption, being in fact responsible for the …

The structural, morphological, and optical properties of the sol–gel derived TiO 2
nanoparticles at different pH and calcination temperature were investigated in the present …

Anatase, a polymorph of titania in the nanocrystalline form, denoted as nc-TiO2, is widely
used for photodegrading organic pollutants in a variety of environmental applications.[1, 2] …

Despite decades of research on the role of intrinsic defects in enhancing the performance of
reduced TiO2 based materials, unambiguous identification of defects responsible for visible …

“Noncompensated np codoping” is established as an enabling concept for enhancing the
visible-light photoactivity of TiO 2 by narrowing its band gap. The concept embodies two …

Aiming at discerning the role of fluorine from that of nitrogen as a dopant in N, F-codoped
TiO2, a series of HF-doped TiO2 photocatalysts were investigated in the decomposition of …
