Photocatalysts are useful for converting sunlight into renewable energy and for decomposition of organic substances. Previous research shows that TiO2 is an effective material to use for environmental purification and photocatalysis. The catalytic activity of TiO2 nanoparticles (NPs) is enhanced on the nanoscale due to the increase in the ratio of surface area to volume. This enhancement is further increased by the modification of the physical and chemical properties due to the adsorption or surface-doping of transition-metal ions. The reactivity of Eu3+ ions with anatase TiO2 nanoparticles under high temperatures and pressures in aqueous fluids has been investigated. A hydrothermal reactor was used to modify the surface of the TiO2 nanoparticles with Eu3+ ions in aqueous fluids under high P-T conditions. The TiO2 NPs were examined using XRD, SEM, and Raman spectroscopy, both before and after hydrothermal treatment. We discuss the vibrational and structural properties of the Eu-surface-doped TiO2 NPs.
