Photocatalytic decolourization of basic green dye by pure and Fe, Co doped TiO2 under daylight illumination

►Pure, Fe and Co doped TiO2 was prepared by simple sol-gel method and characterized ►Tested for decolourization with basic green dye under day light illumination ►Fe-doped TiO2 showed highest photocatalytic activity than other two with 98% in 3 h ►Rate constants (k') are in the order of Fe doped > Co doped > pure TiO2.
