The description of TiO2 synthesis in TiCl4-seeded flames is most often based on phenomenological models that qualitatively reproduce experimental trends terms final production but they do not provide chemical insights into the actual kinetic pathways. Alternatively, thermodynamically-consistent detailed TiCl4 oxidation kinetics are available. However, since have been developed under dry conditions still need to be challenged and validated when employed for flame where presence water molecules may potentially activate hydrolysis. To derive accurate descriptions synthesis, it essential evaluate possible contribution For this, numerical simulations laminar carried out this article using different conversion TiO2. Detailed neglecting hydrolysis shown predict an extremely slow formation particles O2 concentration small. As a consequence, significant underestimation yield observed compared evidences deduced from models. correct behavior, new scheme proposed by combining with five-reaction mechanism describing first steps Conversion found faster more efficient combined scheme, leading log-normal particle size distributions agreement data nanoparticles synthesis.
