Nucleation and growth of mixed vanadium

05/02/2021· The mixed vanadium-titanium oxo-alkoxy (VTOA) nanoparticles were synthesized via sol-gel method in a chemical reactor with ultra-rapid micromixing. The nucleation and growth kinetics and particles size, followed by the static/dynamic light scattering methods, were quite different from those of pure oxo-alkoxy titanium (TOA) and vanadium (VOA) species.

Vanadium and Titanium Mixed Oxide Films:

Vanadium/titanium mixed oxide films were produced using the sol-gel route. The structural investigation revealed that increased TiO2 molar ratio in the mixed oxide disturbs the V2O5 crystalline structure and makes it amorphous. This blocks the TiO2 phase transformation, so TiO2 stabilizes in the anatase phase.
