Synthesis, characterization and photocatalytic properties under visible light of doped and co-doped TiO2-based nanoparticles

Autor: A. El Mragui, Omar Zegaoui, Ikram Daou

Publikováno v: Materials Today: Proceedings. 13:857-865

TiO2-based nanomaterials have been successfully synthesized by the doping and co-doping of TiO2 with transition metals (Cr, Mn, Co and Ni), and (P, Mo) and (Si, W), respectively. The obtained X-ray Diffraction results show that only the anatase phase
