Abstract
Abstract The unprecedented catalytic role of Iron (III) nitrate nonahydrate (Fe (NO 3 ) 3 ·9H 2 O) has been explored in a top-down technique for the synthesis and Iron (III) doping of Titanium dioxide nanoparticles (TiO 2 -NPs). In the experimental procedure, the chosen 1:1 ratio of Fe (NO 3 ) 3 ·9H 2 O and TiO 2 bulk powder is allowed to work hydrothermally in top-down synthesis and Fe-doping of (TiO 2 ) nanoparticles. Field emission scanning electron microscopy (FESEM) shows the particle structure or morphology of the Fe-doped TiO 2 -NPs. Raman and x-ray photoelectron spectroscopy (XPS) is used to study the composition and iron-content at the surface of the synthesized nanoparticles. X-ray diffraction (XRD) pattern has several peaks for α -Fe 2 O 3 corresponds to Iron doping in the synthesized nanoparticles of (TiO 2 ). The current technique provides a practical method for maximum yield and high quality of Fe-doped TiO 2 nanoparticles for its potential photovoltaic and photocatalytic applications in modern technologies.
