摘要
In this paper, a method for the continuous preparation of nanoscaled titania with controlled phase content is presented. The method bases on the MicroJetReactor technology. The synthesis process was carried out by using the hydrolysis of titanium tetraethylate (TET). Synthesis with flow rates to 14ml/min are implemented, and temperatures are varied between 20 and 210°C. Particle size distribution measurements by dynamic light scattering (DLS) show monomodal particle size distributions from 1 to 10nm, stable for more than 24h. There is no correlation between hydrolysis temperature and the particle size distributions.
