  • A novel Spinning Disc Continuous Stir Tank & Settler Reactor (SDCSTSR) has been modeled for continuous synthesis of Titania from its chloride precursor and water in which the desired polymorph, particle size and distribution are controlled by the characteristics of the atomized inlet reagents, disc and tank stir rate. This energy efficient reactor generates seeding nuclei in the aerosol reacting volume which are then deployed for heterogeneous nucleation and particle growth in the metastable reacting volume of the aqueous (sol) process. Once at steady state, the enhanced titanium oxide nanoparticles due to the (OH-)— (H+) chemisorbed on the surface (with surface energy 0.5
