Effect of Transition Metal (Fe, Mn) Ion Doping on TiO2 Nano Particles
In this research, we have studied the doping behaviors of two transition metal ion dopants on the crystal phase, particle sizes, XRD patterns, EDAX spectra, and photoreactivity of TiO2 nanoparticles. The average crystalline size of TiO2 is close to 4 nm Calculated
from (1 0 1) peak by using FWHM method in Scherrer’s equation. Transition metal ion concentrations ranged from 1% to 4 at.%, we report the growth of [Fe, Mn]

TiO2 nanocrystals prepared by Sol–Gel technique, followed by freeze-drying treatment at −30
°C temperature for 12 hrs. The obtained Gel was thermally treated at different temperature like 200 °C, 400 °C, 600 °C, 800 °C. The photoreactivities of transition metal ion-doped TiO2 nanoparticles under UV irradiation were quantified by the degradation of formaldehyde.
Magnetic property has been carried out by VSM. All sample shows room temperature ferromagnetism. It has potential application in field of DMS.
