Novel Phase Transformation Phenomenon of Potassium Teteratitanate Nanofibres Synthesized from H2TiO3

摘要：

Starting from H2TiO3,potassium teteratitanate (K2Ti4O9) nanofibres with the length of several mcrometers and the diameter of 100nm were directly synthesized by solid state reaction. The novel phase transformation and structure change behavior was investigated by the X-ray diffraction technique (XRD), scanning electron microscopy (SEM) in details. In series of hydrothermal reaction,the K2Ti4O9 could transfer to anatase TiO2 and rutile TiO2. Aggregated anatase TiO2 particles and rod-like rutile TiO2 were produced respectively in IM HCl solutions at 160℃ and 220℃. When the 0.01M HCl solution was considered as solvent,the mixture of floral anatase TiO2 and K2Ti4O9 were present together.
