Structural and Magnetic Properties of ⁵⁷Fe‐Doped TiO₂ and ⁵⁷Fe/Sn‐Codoped TiO₂ Prepared by a Soft‐Chemical Process

Abstract

Fe concentrations from 0.1 to 1.0 at.-% and a fixed Sn concentration of 2.0 at.-%. In this process, an aqueous H 2 O 2 solution reacts with iron and titanium or iron, tin, and titanium precursor compounds to produce peroxopolymetallic acids. The structures and magnetic properties of the products were characterized by magnetic-moment measurements, X-ray

Investigation of metal doped mesoporous TiO2 nanostructures for environmental remediation

“…When concentration of Sn increases in TiO 2 lattice the peak shift in Eg mode from 443 cm − 1 to 430 cm − 1 and A 1g mode from 610 cm − 1 to 628 cm − 1 were observed. The shift in raman peak occur due to high lattice defect such as oxygen vacancies can be created by doping of Sn ions [30,31]. ] reveals that the particles are agglomerated with size of about 8 nm 20 nm [35,36].…”
