Photocatalytic water splitting by Ln-doped TiO2 (Ln = Pr, Dy, Sm)
Original language description
Ln-doped TiO2 nanoparticles (Ln = Pr, Dy, Sm) were prepared by the sol-gel low-temperature reaction of titanium tetraisopropoxide with aqueous solutions of organic acid and lanthanide salts. Reaction was carried out with 0.3%, 0.5% and 0.7% lanthanide ions in acidic solution at 100 grdC for 10 hours. XRD analysis revealed the content of crystalline phase of anatase and brookite. Prepared nanoparticles contained crystallites ranging in size from 2.0 to 5.0 nm. Specific surface area of Ln-doped TiO2 ranged from 210-250 m2/g. Differential photocatalytic activity of titania nanoparticles was evaluated at photocatalytic water splitting (of 20% aqueous solution of methanol) in batch quartz reactor. The hydrogen content in the gas phase was measured by mass spectrometry. Co-catalyst, 0.5% of Pt, was deposited on the surface of titania by photochemical method. It was found that the higher photocatalytic activity had sample with 0.7% of Dy and its photoactivity was increased with the content of
