摘要: TiO2 nanoparticles were prepared from titanium isopropoxide in aqueous solution, and the particle size distribution determined as a function of time temperature. We also ZnO using precipitation Zn(Ac)2, Zn(ClO4)2 ZnBr2 isopropanol. In both cases, nucleation growth fast, coarsening aggregation main factors determining distribution. show that Ti02 follows Lifshitz-Slyozov-Wagner rate law for diffusion controlled originally derived colloidal systems with micron particles, where average cubed is proportional to time. dominant parameters controlling kinetics are solvent, precursor salt,
