Keywords Microwave high-pressure synthesis, tetrabutyl titanate, titania, nanoparticle, resonance scattering spectroscopy. The common shortcomings is that the formation of TiO 2 particles is not simultaneous, owing to the concentration diffusion or heat conducting. Microwave is a heating technique by means of molecular vibration in very high speed. In this work, titania nanoparticles prepared in liquid has been proposed by microwave high-pressure method using the chemicals of tetrabutyl titanate. The resonance scattering spectroscopic properties of the nanoparticle have been also reported.
All chemicals are analytical grade.
The solution was dissolved with alcohol, and transferred into a 50ml volume flask, diluted to the mark with the solvent. The effect of water volume on the hydrolysis shows that the microwave reaction is slow when the volume less than 0.5ml, the hydrolysis is speed up at room-temperature when the volume is more than 5ml. The recommendation conditions are 3ml water-480W for 3min. The shape, size, absorption and rigidity of superamolecular or nanoparticles are prime factors to affect the resonance scattering spectra. Different shape for supramolecule or nanoparticle has the different resonance scattering spectra.
