摘要
Mixed phase TiO2 powders of different composition and particle size were subjected to the hydrothermal reaction with 10 M NaOH It was found that the anatase phase component of the starting material is easily converted to trititanate nanotubes at 140 C At this temperature the I-utile phase remains unreacted however at 170 C it reacts to form trititanate plates and belts When the reaction time is increased to 7 days all the TiO2 is converted to trititanate and the morphology is exclusively nanoplates and belts with the tube phase destroyed Many researchers have observed some heterogeneity in their reaction products but have mainly focussed on the nanotubes We observed that the tubes are only prepared from the anatase phase component of a TiO2 precursor whereas the rutile component produces trititanate plates and sheets irrespective of the reaction length The particle siz
