Synthesis and characterization of undoped and doped tio2 photocatalyst

Undoped and doped TiO2 photocatalyst where characterized by FTIR, DRS, BET SEM and XRD. From these studies we investigated the optical absorption (λmax), functional group, particle size, surface morphology and elementary composition of undoped and doped TiO2. The dopants used where four atomic percentage of Cr3+, Fe3+.
