Abstract

Y₂Ti₂O₇ nanoparticles (0.3 mol%) have been successfully synthesized by the co-precipitation process. The samples, adjusted to pH7 with ammonia solution as catalyst and calcined at 700~900 °C, exhibit very fine particles with close to spherical shape and average size of 10-30 nm. It was possible to control the size of the synthesized Y₂Ti₂O₇ particles by manipulating the conditions. The Y₂Ti₂O₇ nanoparticles were coated on a glass substrate by a dipping coating process with inorganic binder. The Y₂Ti₂O₇ solution coated on the glass substrate had excellent adhesion of 5B; pencil hardness test results indicated an excellent hardness of 6H. The thickness of the thick film was about 30 μm. Decomposition of MB on the Y₂Ti₂O₇ thin film shows that the photocatalytic properties were excellent.
