MSU Graduate Theses
Anatase TiO2 has been shown to be potential applications for photo-remediation of chemical waste as well as for photocatalytic splitting of water. The catalytic properties of TiO2 materials can be modified by doping with lanthanide (Ln) ions. In order to minimize the distortion and/or change of the structure of TiO2 nanoparticles, surface doping of anatase TiO2 nanoparticles (~ 14 nm) with several Ln ions (Nd3+, Gd3+, Eu3+, Yb3+) has been successfully made. X-ray diffraction (XRD) and Raman characterization shows that the anatase phase of treated nanoparticles is well preserved. Scanning electron microscopy (SEM) shows that the majority of the nanoparticles …
