The principal aims of this work were to synthesise visiblelight-sensitive
TiO
powders with interstitial molecular structures
using different types of nitrogen dopants and to investigate effects
of nitrogen dopants on the degradation of an organic pollutant.
The three investigated dopants were diethanolamine (DEA), triethylamine
(TEN) and urea. To test the photocatalytic activity of
the obtained interstitial N-doped TiO
2
, 2-chlorophenol (2-CP) was
selected as an organic probe due to its high toxicity and its wide
use in many industrial activities. In this work, authors investigated
the alterations of interstitial N-doped TiO
2
properties, such as
strong absorption in the UV–visible (UV–vis) light region, redshift in
adsorption edge, degree of crystallisation and mixture of two phase
structures (anatase and rutile) of the titania obtained fromdifferent
dopants. Degradation and mineralisation of 2-chlorphenol using
each type of interstitial N-doped TiO
2
2
were determined. Relations
between properties of the N-doped TiO
and kinetic parameters in
the photocatalytic degradation of 2-chlorophenol were also examined
in this work.
