Study of synergistic effect of Sc and C co-doping on the enhancement of visible light photo-catalytic activity of TiO2

Sc and C co-doped TiO2 nanoparticles were synthesized through simple sol-gel method, which decreased the crystallite size of the nanoparticles and increased the lifetime of the photo-induced charge carriers. The Sc and C co-doped samples showed significantly high photoactivity as compared to the single C-doped TiO2 nanoparticles.
