Anatase phase TiO2 nanorods modified
with perylene nanoparticles (PeNPs) (PNR520) showing excellent
photocatalytic activity under sunlight were synthesized. Titanium
isopropoxide [C12H28O4Ti] and aqueous KOH solution were
hydrothermally treated to form hydrogen titanate and were calcined
at 520°C to get TiO2 nanorods. PeNPs were prepared from
perylene-3,4,9,10- tetracarboxylic dianhydride using D-glucosamine
hydrochloride. Phase transition from hydrogen titanate to pure
anatase phase TiO2 was confirmed by X-ray diffraction analysis. high
resolution transmission electron microscopic analysis shows that the
anatase phase TiO2 consists of nanorods. Photocatalytic activities
of the samples were assessed by studying the photocatalytic
degradation of rhodamine B. Study reveals that TiO2 nanorods
modified with PeNPs could completely degrade common endocrine
disruptors such as 4-chlorophenol, resorcinol, and salicylic acid
under sunlight and are more efficient than the commercial
photocatalyst Degussa P25.
