In summary, we have reported the synthesis of 1%, 2% and 4% Fe,Co doped TiO2 powders successfully prepared via sol–gel synthesis and controlled calcinations. XRD for Fe, CO doped TiO2 indicates dopant concentration effects phase transition temperature. The magnetic susceptibility of the Fe,Co doped TiO2 nanopowder increases with increase in doping concentration. Fe,Co doped TiO2 exhibits Para magnetism at room temperature. The photocatalytic degradation of formaldehyde has been successfully demonstrated using a 250 V UV lamp with TM doped TiO2 nano powder in a specific experimental setup. The degradation rate increases linearly with dopant content increases. This indicates that the photocatalytic reaction in this experiment was effected by dopant concentration. The results obtained in this research contribute to the understanding of multiple doped transition metal ions in TiO2 nanoparticles can lead the efforts of enhancing their environmental application.
