Photocatalytic degradation of 2-propanol over metal-ion-loaded titanium(IV) oxide under visible light irradiation: Effect of physical properties of nano-crystalline titanium(IV) oxide

▶ Metal-ion modified TiO2 samples (M+/TiO2's) were prepared using adsorption method. ▶ M+/TiO2's were used for photocatalytic degradation of 2-propanol. ▶ Rh3+/TiO2 exhibited higher levels of activity under visible light irradiation. ▶ Balance of surface area and crystallinity of TiO2 is important in Rh3+/TiO2.
